The data is structured in visits. Each visit (ex: S2) is divided into several series of images in different filters. The number after each visit gives the number of the series (ex: S2.001 in filter F125LP). Some visits are spread over 1 or 2 days while some days have zero visits.
The name of each file (fits or jpeg) containts the first 3 letters of the observed planet, the day of teh year and year of observation, the time of observation and the instrument (ACS).
Only the images in the jpeg format and the movies (.mov) are accessible to the public. The fits files require a username and password that we can provide on request.
