Re: fun with coadding images on Disk Set 19

[Tom Droege <tdroege@veriomail.com>]

I tried the median combine on the images of DS192 using every third 
image.  It looked fair.  I then tried the same thing on a later data 
set.  It looked awful with lots of diagonal streaking.  So I guess I have 
improved the alignment enough that this will not work.
