/* ET I Ephemeris time measured in seconds past J2000. */
/* STRING O A standard calendar representation of ET. */
/* $ Detailed_Input */
/* ET is an epoch measured in ephemeris seconds */
/* past the epoch of J2000. */
/* $ Detailed_Output */
/* STRING is a calendar string representing the input ephemeris */
/* epoch. This string is based upon extending the */
/* Gregorian Calendar backward and forward indefinitely */
/* keeping the same rules for determining leap years. */
/* Moreover, there is no accounting for leapseconds. */
/* To be sure that all of the date can be stored in */
/* STRING, it should be declared to have length at */
/* least 48 characters. */
/* The string will have the following format */
/* year (era) mon day hr:mn:sc.sss */
/* Where: */
/* year --- is the year */
/* era --- is the chronological era associated with */
/* the date. For years after 999 A.D. */
/* the era is omitted. For years */
/* between 1 A.D. and 999 A.D. (inclusive) */
/* era is the string 'A.D.' For epochs */
/* before 1 A.D. Jan 1 00:00:00, era is */
/* given as 'B.C.' and the year is converted */
/* to years before the "Christian Era". */
/* The last B.C. epoch is */
/* 1 B.C. DEC 31 23:59:59.999 */
/* The first A.D. epoch (which occurs .001 */
/* seconds after the last B.C. epoch) is: */
/* 1 A.D. JAN 1 00:00:00.000 */
/* Note: there is no year 0 A.D. or 0 B.C. */
/* mon --- is a 3-letter abbreviation for the month */
/* in all capital letters. */
/* day --- is the day of the month */
/* hr --- is the hour of the day (between 0 and 23) */
/* leading zeros are added to hr if the */
/* numeric value is less than 10. */
/* mn --- is the minute of the hour (0 to 59) */
/* leading zeros are added to mn if the */
/* numeric value is less than 10. */
/* sc.sss is the second of the minute to 3 decimal */
/* places ( 0 to 59.999). Leading zeros */
/* are added if the numeric value is less */
/* than 10. Seconds are truncated, not */
/* rounded. */
/* $ Parameters */
/* None. */
/* $ Exceptions */
/* Error free. */
/* 1) If the input ET is so large that the corresponding */
/* number of days since 1 A.D. Jan 1, 00:00:00 is */
/* within 1 of overflowing or underflowing an integer, */
/* ET will not be converted to the correct string */
/* representation rather, the string returned will */
/* state that the epoch was before or after the day */
/* that is INTMIN +1 or INTMAX - 1 days after */
/* 1 A.D. Jan 1, 00:00:00. */
/* 2) If the output string is not sufficiently long to hold */
/* the full date, it will be truncated on the right. */
/* $ Files */
/* None. */
/* $ Particulars */
/* This is an error free routine for converting ephemeris epochs */
/* represented as seconds past the J2000 epoch to formal */
/* calendar strings based upon the Gregorian Calendar. This formal */
/* time is often useful when one needs a human recognizable */
/* form of an ephemeris epoch. There is no accounting for leap */
/* seconds in the output times produced. */
/* Note: The calendar epochs produced are not the same as the */
/* UTC calendar epochs that correspond to ET. The strings */
/* produced by this routine may vary from the corresponding */
/* UTC epochs by more than 1 minute. */
/* This routine can be used in creating error messages or */
/* in routines and programs in which one prefers to report */
/* times without employing leapseconds to produce exact UTC */
/* epochs. */
/* $ Examples */
/* Suppose you wish to report that no data is */
/* available at a particular ephemeris epoch ET. The following */
/* code shows how you might accomplish this task. */
/* CALL DPSTRF ( ET, 6, 'F', ETSTR ) */
/* CALL ETCAL ( ET, STRING ) */
/* E1 = RTRIM ( STRING ) */
/* E2 = RTRIM ( ETSTR ) */
/* WRITE (*,*) 'There is no data available for the body ' */
/* WRITE (*,*) 'at requested time: ' */
/* WRITE (*,*) ' ', STRING(1:E1), ' (', ETSTR(1:E2), ')' */
/* $ Restrictions */
/* One must keep in mind when using this routine that */
/* ancient times are not based upon the Gregorian */
/* calendar. For example the 0 point of the Julian */
/* Date system is 4713 B.C. Jan 1, 12:00:00 on the Julian */
/* Calendar. If one formalized the Gregorian calendar */
/* and extended it indefinitely, the zero point of the Julian */
/* date system corresponds to 4714 B.C. NOV 24 12:00:00 on */
/* the Gregorian calendar. There are several reasons for this. */
/* Leap years in the Julian calendar occur every */
/* 4 years (including *all* centuries). Moreover, the */
/* Gregorian calendar "effectively" begins on 15 Oct, 1582 A.D. */
/* which is 5 Oct, 1582 A.D. in the Julian Calendar. */
/* Therefore you must be careful in your interpretation */
/* of ancient dates produced by this routine. */

/* IN I Input string. */
/* MARKER I Marker to be replaced. */

/* SIGDIG I Significant digits in replacement text. */
/* FORMAT I Format: 'E' or 'F'. */

/* $ Detailed_Input */
/* IN is an arbitrary character string. */
/* MARKER is an arbitrary character string. The first */
/* occurrence of MARKER in the input string is */
/* to be replaced by VALUE. */
/* Leading and trailing blanks in MARKER are NOT */
/* significant. In particular, no substitution is */
/* performed if MARKER is blank. */
/* VALUE is an arbitrary double precision number. */
/* SIGDIG is the number of significant digits with */
/* which VALUE is to be represented. SIGDIG */
/* must be greater than zero and less than 15. */
/* FORMAT is the format in which VALUE is to be represented. */
/* FORMAT may be any of the following: */
/* FORMAT Meaning Example */
/* ------ ----------- ---------------- */
/* E, e Scientific 3.14159E+03 */
/* (exponent) */
/* notation */
/* F, f Fixed-point 3141.59 */
/* notation */
/* $ Detailed_Output */
/* OUT is the string obtained by substituting the text */
/* representation of VALUE for the first occurrence */
/* of MARKER in the input string. */
/* The text representation of VALUE is in scientific */
/* (exponent) or fixed-point notation, depending on */
/* having the value of FORMAT, and having the number */
/* of significant digits specified by SIGDIG. */
/* The representation of VALUE is produced by the */
/* routine DPSTRF; see that routine for details */
/* concerning the representation of double precision */
/* numbers. */
/* OUT and IN must be identical or disjoint. */
/* $ Parameters */
/* MAXLFD is the maximum expected length of the text */
/* representation of a formatted double precision */
/* number. 56 characters are sufficient to hold any */
/* result returned by DPSTRF. (See $Restrictions.) */
/* $ Files */
/* None. */
/* $ Exceptions */
/* Error Free. */
/* 1) If OUT does not have sufficient length to accommodate the */
/* result of the substitution, the result will be truncated on */
/* the right. */
/* 2) If MARKER is blank, or if MARKER is not a substring of IN, */
/* no substitution is performed. (OUT and IN are identical.) */
/* $ Particulars */
/* This is one of a family of related routines for inserting values */
/* into strings. They are typically to construct messages that */
/* are partly fixed, and partly determined at run time. For example, */
/* a message like */
/* 'Fifty-one pictures were found in directory [USER.DATA].' */
/* might be constructed from the fixed string */
/* '#1 pictures were found in directory #2.' */
/* by the calls */
/* CALL REPMCT ( STRING, '#1', N_PICS, 'C', STRING ) */
/* CALL REPMC ( STRING, '#2', DIR_NAME, STRING ) */
/* which substitute the cardinal text 'Fifty-one' and the character */
/* string '[USER.DATA]' for the markers '#1' and '#2' respectively. */
/* The complete list of routines is shown below. */
/* REPMC ( Replace marker with character string value ) */
/* REPMD ( Replace marker with double precision value ) */
/* REPMF ( Replace marker with formatted d.p. value ) */
/* REPMI ( Replace marker with integer value ) */
/* REPMCT ( Replace marker with cardinal text) */
/* REPMOT ( Replace marker with ordinal text ) */
/* $ Examples */
/* 1. Let */
/* IN = 'Invalid operation value. The value was #.' */
/* Then following the call, */
/* CALL REPMF ( IN, '#', 5.0D1, 2, 'E', IN ) */
/* IN is */
/* 'Invalid operation value. The value was 5.0E+01.' */
/* 2. Let */
/* IN = 'Left endpoint exceeded right endpoint. The left */
/* endpoint was: XX. The right endpoint was: XX.' */
/* Then following the call, */
/* CALL REPMF ( IN, ' XX ', -5.2D-9, 3, 'E', OUT ) */
/* OUT is */
/* 'Left endpoint exceeded right endpoint. The left */
/* endpoint was: -5.20E-09. The right endpoint was: XX.' */
/* 3. Let */
/* IN = 'Invalid operation value. The value was # units.' */
/* Then following the call, */
/* CALL REPMF ( IN, '#', 5.0D1, 3, 'F', IN ) */
/* IN is */
/* 'Invalid operation value. The value was 50.0 units..' */
/* 4. In the above example, if SIGDIG is 1 instead of 3, IN becomes */
/* 'Invalid operation value. The value was 50 units.' */
/* 5. Let */
/* IN = 'Invalid operation value. The value was #.' */
/* Then following the call, */
/* CALL REPMF ( IN, '#', 5.0D1, 100, 'E', IN ) */
/* IN is */
/* 'Invalid operation value. The value was */
/* 5.0000000000000E+01.' */
/* Note that even though 100 digits of precision were requested, */
/* only 14 were returned. */
/* 6. Let */
/* MARKER = '&' */
/* NUM = 23 */
/* CHANCE = 'fair' */
/* SCORE = 4.665D0 */
/* Then following the sequence of calls, */
/* CALL REPMI ( 'There are & routines that have a ' // */
/* . '& chance of meeting your needs.' // */
/* . 'The maximum score was &.', */
/* . '&', */
/* . NUM, */
/* . MSG ) */
/* CALL REPMC ( MSG, '&', CHANCE, MSG ) */
/* CALL REPMF ( MSG, '&', SCORE, 4, 'F', MSG ) */
/* MSG is */
/* 'There are 23 routines that have a fair chance of */
/* meeting your needs. The maximum score was 4.665.' */
/* $ Restrictions */
/* 1) The maximum number of significant digits returned is 14. */
/* 2) This routine makes explicit use of the format of the string */
/* returned by DPSTRF; should that routine change, substantial */
/* work may be required to bring this routine back up to snuff. */
