0730	Arrive - play with church music until ~815
	beginning in /findMSe/ stuff
0847	tweaked up histgraph.g a little, still a big problem when hitting
		the nasty section in IRIS... BIG problem. YUCK!
0905	weighting is WRONG on B4 collected IRIS image... trying to fix
	going to fix masking IN the histgraph script... sloppy but works?
1016	way to make mask for IRIS image, on a per-field basis:
	- regrd('IRIS_B4_regrid_61_mask.fits','good_ms1_tau_61_totalmoment.fits','good_ms1_IRIS_61_mask')
1044	PROPER way to get iris mask info is to regrid to match moment map of
		field and USE the IRIS_61 data, so that regridding matches
	-all B1-B4 IRIS have appropriate masks on the 6.1' scale now
1136	learned how to use 'montage' command, and can make single ps files
		with ALL 9 graphs.
	completed ms1, moving on to ms2...
1205	lunch w/ Katie and Jason
1240	back from lunch. continuing on ms2, and on ms3
	OOOOOPS!  IRIS data is now unconvolved! I re-combined it without
		doing the convolution. it's "actual" resolution is way too
		high. And everything is wrooooonnnngggg.
	Fixing IRIS convolution in each band with:
	imc := im.convolve2d(major='13.74arcmin',minor='13.74arcmin')
1430	this convolution doesn't work... when running on whole image it all
		comes out as nan. when running on individual tiles it's fine,
		but we need the Whole Thing.
1445	Trying to change all masked (and negative) values in the IRIS B4 data
		to -10, and running convolve2d on that
	Runs WAY fast!
1513	lots of problems with regridding to 6.1', and matching IRIS data up,
		with mask, with convolution, etc. eep. After this song I'm
		going to sit outside for a few minutes, in the sunshine...
	13.74' conv2d must be done on IRIS before 6.1' regridding! (i think)
1705	DJ helped with masking, once and FOR ALL!
	here's how:
	#convert IRIS regridded(GASS) data from fits to img (the fixed one)
	im := imagefromfits(infile='IRIS_B4_regrid_GASS_m.fits',outfile='IRIS_B4_regrid_GASS_m.img')
	im.done()
	im := image('IRIS_B4_regrid_GASS_m.img')
	im.calcmask('$im>-10')
	
	IRIS_B4_regrid_GASS_withmask.fits NOW HAS THE MASK IN IT! HOORAY!
1715	should work on regridding to 6.1' next... and update the IRIS images
1720	heading out - bicycling to blueberries with Sophia!
