Gaia scanning-law movie
This movie (46.8M) shows the number of field transits (so for both fields of view).
The movie has three intervals, interesting features to note are:
The movie was made by scanning the central positions of each pixel of a healpix map of depth 8 (3.1 million pixels) with the scanner in AGISLab and taking the number of SM-observations (of which there is just 1 per field transit). Then the map was projected into a Hammer-Aitoff plot using the graphics library in GaiaTools.
The picture, in particular, shows the number of field transits in ICRS after 5 years.
