0930	Arrive. Pleasant walk in with Sophia and Courtney.
	Going to start trying to mask the pixels....
		to 0 all the pixel masks, use:
		- im := image('SFD_i100_ngp_regrid.img')
		- im.replacemaskedpixels(0.0,update=T)
		- im.tofits('ngp_1.fits')
	and to combine these:
		- im1 := image('ngp_1.fits')
		- im2 := image('sgp_1.fits')
		- im1a := im1.getchunk()
		- im2a := im2.getchunk()
		- im3a := im1a+im2a
		- im3:=imagefromarray(outfile='SFD_all_regrid.img',pixels=im3a)
		- im3.tofits('SFD_all_regrid.fits')
	other than the triangles, this looks good.
1010	heading up to radio astronomy electronics talk...
1120	back from talk. going to crop reference moment map image down a
		little, and try to eliminate triangles...
	trying to regrid to match to this crop: [hindsight: crops are all BAD]
		- ima := im.getchunk(100,2397)
		of the moment map
	in _crop100_regrid files...
	regrd.g takes about 90 seconds to regrid one half of the SFD data
	...results still have annoying triangles!
	try cropping by 200 pixels on each edge... crop200 files
	... results STILL have annoying triangles...
1200	lunchtime
1235	back from lunch...
	making moment of cube 001 (from -250 to -240, 13 planes) takes about
		3 minutes or so, but DESTROYS computer functionality when it
		is going.
1330	orientation/picture-taking
1530	meet w/ jay/dj/sophia...
1620	back to dungeon, showing sophia around/etc
1730	head over to the cookout with Sophia, Jonathan, and Courtney
