Given the stamp of the 4x4 pixel array, there is an area of about 70" around the edges where the sensitivity goes down. There should be a map for this, since ADMIT will need it to work in a noise flat image.

the -w flag in the gridder program has been implemented. Remaining issue to be solved it the rms_noise flag, since this can make a small different in the weight map.

The lmtoy_reduce and combine script now also compute a "wt2" and "wt3" map. In addition the WCS has been fixed

The wt2 and wt3 map compare quite well, the wtr map is consistent with them being the same.
The wt map however has a ~10% higher RMS (lower WEIGHT). I don't understand this yet.
