0835	Arrive. First thing to do: figure out how to do math on images...
1115	oops, forgot to be updating this. been reading/experimenting with
		math in aips++/glish... found some useful commands, like:
			g3 := imagefromfits('g3.img','g.fits')
		  which takes g.fits and makes it into an aips++ image file
		  called g3. then you can do math/etc with it, like this:
			im := imagecalc(pixels='g3.img+10')
		  to add 10 to it, for example.
	also worked for an hour or so on stuff for Mihos, old simulations
		from PNe stuff, and figuring out why PNe16's 7m results
		look so different from PNe26's 7m results. Ugh, lots of
		digging through notes and data files.
1200	found agreement on actual quantitative values in the moment maps
		between my progress and the Lockman/Condon paper... in
		-230km/s to -130km/s, matched peak of 6.9E19 cm^-2, which
		they say is about 0.25 of max value in that area (over
		all vels), which I calculate as about 0.28 of my max val.
1210	lunch w/ Danielle and Katie, outside of science center. pleasant.
1250	back from lunch
	going to work on how to match IR and HI data, by regridding/etc...
		reading/skimming SFD98 paper (saved, too)...
1340	also downloading original SFD98 data from website:
		http://astro.berkeley.edu/~marc/dust/data/data.html
	/export/home/ninkasi/scratch/sjanowie/SFD/
		contains original SFD data from website
1450	fits headers are nightmarish. the file from Lockman,
		SFD_i100_conv9p8m.fits
	has two sets of coord-spacing/info in its FITS header....
		one of them matches with the FLS data, but the other doesn't,
		and ds9 doesn't think they match. neither does aips++,
		therefore, neither do i.
	for now, going to grab small-ish chunk of SFD/GASS and work out
		pixel mumbo-jumbo for it... call it small...
1500	coffee break upstairs
1540	back. dj/toney suggested using 'fv' to get at the fits headers
	first, though, working on matching up small image, for practice...
	making new sub-cubes, all velocities, around:
		01:10:40  -6:16:23 (J2000)
	called small50/small25/small10, by sizes, 50x50,25x25,10x10,etc
1605	FLS/SFD images match, now that i took the CD0_0,0_1,1_0,1_1 out of
		the fits header for the SFD image. double-checked the match
		in ds9, and it all looks good.
1715	finally figured out how to look for correlations in images/etc, it
		is all in the code sample that jay gave me to begin with...
		ha. i've implemented some of it now, in corr.g
	things to do soon...
		fix units on moment maps to all be in N_HI = xxx cm^-2
			(i.e. add this into vsubmom.g script!)
		try correlations with different v. ranges, make script
			run better/swifter/etc
		for now, play with FLS/SFD, since those images are already
			re-gridded to be the same. eventually figure out how
			to do that re-gridding with SFD/GASS...
1735	departing.
