I'm not sure the error reported yesterday is reproducible. Tonight, I started a complete re-mapping of the entire survey. The new mapping will include beam-smoothed maps and more complete header parameters. I need to re-check the L111 mapping. It looks like the region with NGC 7538 in it did alright, but the southeast region didn't do so well. The combined maps are probably better than in any previous iteration, though. Tomorrow's tests will include L024 presumably. It's time to get to work on this stuff. There is definitely a reasonably efficient way to go through all of this stuff; the most difficult part is post-facto error checking. Here are some awk commands I found useful (the \'s are because of VI): `` awk '{printf( $0); if ($2 != 0){ printf(" %4i%4i",$4-443,$5-207) }; if($4!=0){printf(" %4i,%4i",$2-272,$3-742)}; printf("n") }' align/l111_fitslist_shiftfind.txt`` awk '{print $6,$7}' align/l111_fitslist_shiftfind.txt > align/shifts_all_lb.txt One important point: I had to add a parameter to the header file to say whether the current pointing model was used or not. It matters when applying the offsets. Note that since I'm using the pointing model to make all the individual maps, we actually have to stick with this current set of pointing models for all coaligned maps. The current models:
# Definition of coefficientts:# start/end mjd are the start/end modified Julian date of a given pointing model# the 'a' coefficients are for the AZIMUTH OFFSET, the b coefficients are for the ZENITH ANGLE OFFSET# a0/b0 are constants (e.g. the mean)# [ab][12] are the 1st and 2nd coefficients of Azimuth. They have been fiated to zero for most of# the past year or three.# [ab][34] are the 1st and 2nd coefficients of Zenith Angle.# A 'pointing model' is therefore something like this:# azoff = a0 + a3*alt + a4*alt^2# altoff = b0 + b3*alt + b4*alt^2## It is important that the start_mjd/end_mjd be in ascending order## WARNING: LATER THAN JULY 2007 DEFAULTS TO JULY 2007 WHICH WILL PROBABLY RESULT IN ERRORS!# I don't have a September 2007 model yet.## start_mjd end_mjd a0 a1 a2 a3 a4 b0 b1 b2 b3 b4 realdate 53522.5 53582.5 -9.2413685 0.0 0.0 -0.0066354359 -0.0015110883 7.0392221 0.0 0.0 -0.053635657 -0.00047042481 20050601 53614.5 53643.5 84.969583 0.0 0.0 -2.4339154 0.016300937 126.00164 0.0 0.0 -2.4424431 0.015455417 20050901 53887.5 53947.5 9.5305281 0.0 0.0 -0.053191181 -0.0029300592 0.13425019 0.0 0.0 0.48160040 -0.0092814256 20060601 53979.5 54008.5 -98.980381 0.0 0.0 0.65354164 -0.012414466 52.841380 0.0 0.0 1.6705743 -0.020893018 20060901 54101.5 54252.5 -99.078392 0.0 0.0 0.105270 -0.005943491 86.896333 0.0 0.0 0.54257415 -0.011919129 20070101 54252.5 54288 -103.03831 0.0 0.0 0.20972540 -0.0060336987 100.74491 0.0 0.0 0.0099012827 -0.0033331895 20070601# 54288 54313 -99.078392 0.0 0.0 0.10527000 -0.0059434911 86.896333 0.0 0.0 0.54257415 -0.011919129 20070707 54288 54313 -98.803883 0.0 0.0 0.11810246 -0.0051207995 91.720516 0.0 0.0 0.18953269 -0.0078189793 20070707 54313 54500 -99.078392 0.0 0.0 0.10527000 -0.0059434911 86.896333 0.0 0.0 0.54257415 -0.011919129 20070707mjd2date,53522.5 ,y,m,d & print,y,m,dmjd2date,53614.5 ,y,m,d & print,y,m,dmjd2date,53887.5 ,y,m,d & print,y,m,dmjd2date,53979.5 ,y,m,d & print,y,m,dmjd2date,54101.5 ,y,m,d & print,y,m,dmjd2date,54252.5 ,y,m,d & print,y,m,dmjd2date,54288 ,y,m,d & print,y,m,d
