calin is a calibration and analysis package for data from arrays of imaging atmospheric Cherenkov detectors (IACTs). Its main purpose is as a development platform for calibration algorithms for CTA and in particular for NectarCam.

calin is a (French) word that my three-year-old daughter says a lot. Here it isn't meant to mean anything specific, but to evoke the word "calibration". Since acronyms abound in astronomy it could at a stretch stand for "calibration and analysis for large IACT networks", but that wasn't the original motivation.
