Some notes on the files here:
addmumurv.tcl -- tcl script to use Johnson and Soderblum get mua,mud,RV from 
				other quantities (ra,dec, distance, u,v,w)
addreflex.tcl -- adds last two columns to a gs file -- input a distance
		and assumes all stars at that distance.
		The inf (infinite distance) is 1Mpc (1000 kpc)
		Other distances tried: 15 kpc and 6 kpc.
awkxgc -- removes objects in a circle (not cos dec corrected) of 1/2 degree
		around 3 globulars: NGC 5466, 5272, 5904
		
cntpm.tcl -- plots arrows in the direction of the average PM in every
		box.
colormag.tcl -- the loadimage program to make a greyscale rep. of data
gs8all -- all matches between SDSS and Gaia with Gaia pm errors < 0.8 mas/yr
gs8all.nogc  -- same as above but remove 0.5 deg around three globulars
gs8all.nogc.sol15  -- append on as cols 19,20 (1-indexed) assuming all at 15 kpc
gs8all.nogc.sol15.m18  -- subset of above with sdss mag g_0 < 18
gs8all.nogc.sol15.m18195 -- subset of 2 above with 18 < g_0 < 19.5
gs8all.nogc.sol6  -- append on as cols 19,20 assuming all at 6 kpc
gs8all.nogc.sol6.m18  g_0 < 18
gs8all.nogc.sol6.m18195  18 < g_0 < 19.5
gs8all.nogc.solinf  -- add on pmra,pmdec corrected assuming d= 1000 kpc
gs8all.nogc.solinf.m18
gs8all.nogc.solinf.m18195
gsall.match.new  all the matches between SDSS MSTO and 
			Gaia 130 < ra < 250, -5 < dec < 45.
gs.info  explanation of columns for all the gs8all.. files (0-indexed)
nsetnew.dat  all the SDSS selected MSTO stars (no match to Gaia yet)
