Changes between Version 11 and Version 12 of Durham_MDS_Testing3

v11	v12
34	34	Points to note: the stars on Heather's stack show a scale error wrt SDSS. Pauls nightly stack before the clipping fix was problematic. After the fix the photometry is much improved, but still shows more scatter than the original data.
35	35
	36	Below is an example of a remaining problem with the clipping. This is the weight map round a star on Paul's fixed 25532 8-exposure stack. Successive gradations in the levels indicate how many warps are contributing to a particular pixel (with at most 8 warps it is easy to see the difference in levels) - brighter means fewer warps. Notice how, as one approaches the star radially, successively fewer and fewer warps appears to contribute (note: in the very centre the star is no longer sky noise dominated so the quantisation is no longer seen - I have set this area to be white).
