WARNING: these files are intended to be used ONLY WITH L1B data files from the
         nominal MSG+0415 satellite (i.e. with a sub-satellite longitude of 41.5°E)

Files are available for 1 km and 3 km resolutions (<RES>). For each resolution:

5 float32 binary files, fill value = -999.:
- MSG+0415.<RES>.lat : latitude  (degrees, [ -90, +90], positive northwards)
- MSG+0415.<RES>.lon : longitude (degrees, [-180,+180], positive eastwards)
- MSG+0415.<RES>.zen : view zenith (degrees, [0,90])
- MSG+0415.<RES>.azi : view azimuth (degrees, [0,360], clockwise from North)
- MSG+0415.<RES>.pas : pixel area size (km^2)

1 HDF4 file:
- MSG+0415.<RES>.hdf : 5 SDS with the same content as the 5 binary files
