| | 23 | * Fixed bug in generation of skycell and mosaicked camera configurations that was preventing warp update. |
| | 24 | * Tracked down bug in publishing to MOPS: sources with NAN magnitudes are not being propagated, but most sources in the CMF files have NAN magnitudes, and those that don't appear to be spatially correlated (!?). Gene suspects this issue has been solved by a recent fix to psphot. |
| | 25 | * Image subtraction with dual convolution |
| | 26 | * Seems to be a problem in math for the unconstrained least-squares problem: reworking the least-squares matrix in a simpler manner yields a solution that does much better! |
| | 27 | * Fixed sign error in penalty function. |
| | 28 | * Created more complete test set |
| | 29 | * ISIS_RADIAL, PENALTY=1, SKY.ERR=SYS.ERR=0, DUAL=TRUE with orders (1.8,2)(3.3,2)(5.8,2)(10.2,2) very successful in producing zero sources in output photometry except for large mis-aligned input PSFs. |
| | 30 | * Using widths = (pi/2)^i^ for i = 1..6 and order = 2 reduces the problems with large input PSFs, but has some nasty over-subtractions. |
| | 31 | * Comparing with hotpants. ppSub with dual convolution looks better (as one would hope: more free parameters) |
| | 32 | * ppSub about twice the running time of hotpants, but doing 4x the convolutions (2 input images, 2 variance maps) |
| | 33 | * Wrote up on wiki: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ppSub_vs_Hotpants |
| | 34 | * Fixed bug in update of diffs: wasn't reading in the old kernel, so was calculating a new one. ppSub on trunk now produces identical output when doing an 'update'. |
