 *
 * Format explanation: all lines starting with a * are comments and you can also have empty lines
 *
 * Field 1: Gross weight of the glider, excluded ballast, when the values were measured
 * Field 2: Max ballast you can load (water). It will add wing loading, separately
 * Field 3-4, 5-6, 7-8  are couples of  speed,sink rate  in km/h and m/s .
 * 	these values are used to create an interpolated curve of sink rates
 * Field 9: NEW! Normally winpilot does not have this value. Put here at all cost the glider
 *          surface area in squared meters (m2). If the polar curve you are using does not have
 *          this value, go on wikipedia to find the wing area for that glider and add it after a comma.
 *
 * Here is the REAL polar used internally, that you have to create or change, for a glider
 * that during test flight was weighting 330kg including pilots and everything, that can load
 * extra 90 liters of water ballast, that at 75km/h has a sink rate of 0.7 m/s , at 93 km/h of 0,74
 * at 185 km/h sinks at 3.1 m/s and finally that has a wing surface of 10.6 m2.
 * Thus, the polar was calculated with a default wing loading of 31.1 kg/m2

 * So this is an example
 *
 * 330,	90,	75.0,	-0.7,	93.0,	-0.74,	185.00,	-3.1, 10.6
