The DATESOBS files are not official Planck products but are provided for the convenience of the community. They contain timing information sampled by UTC day for investigation of inter-survey source variability and comparison with external observations.
There are 27 files for all combinations of instrument band and survey. The files themselves are:
- FITS format, with data in the first extension
- RING-ordered HEALPIX
- NSIDE 1024 for LFI, and 2048 for HFI
They contain two fields:
- DATESOBS - list of UTC days on which the pixel was observed.
- NUMOBS - The number of UTC days on which the pixel was observed.
