MD02.refstack.20120927
v33 v34 19 19 20 20 Exposure reprocessing was done for only a limited number (~150) of the best images from 2010+2011 to provide a balance of N input warps versus best seeing, excluding exposures with large background, low zeropoints and large elongation. Processing chip-warp and the refstack itself has the same label, data_group 21 * label: MD02.refstack.20120927 --> ''once set as active refstack for diffims, stack label will change to MD02.refstack'', chip/cam/warp label will remain the same21 * label: MD02.refstack.20120927 --> MD02.refstack ''for stack label will change once set as active refstack for diffims, chip/cam/warp label will remain the same'' 22 22 * data_group: MD02.refstack.20120927 23 23 … … 90 90 The center skycell often has a problem with worse seeing so added skycell.033 for comparison. Overall very little improvement in FWHM is possible (~0.2 pixels with minimum number of inputs as with other fields), but now depth is similar with other MD. Even worse, the FWHM_MAJOR can be unstable/variable on similar, repeated runs and should probably use IQ_FW1 as noted before.. also see the full field map below with comparison to the previous MD02 set. 91 91 92 93 92 == Problems == 94 93 * generally edge skycells have issues, need better containment of those still.
