Changeset 42842 for trunk/psphot/src/psphotRoughClass.c

Timestamp:

Message:

add psphotFindFeatures; enable forced-photometry between cameras; do NOT skip negative-flux sources in full-force photometry; make PSF residual component generation more robust: IRLS vs median; exclude pixels with poor values (scaled value > 1.5, relative to normalized PSF); exclude pixels with too few inputs (<5); allow PSF clump to use clipped stats or robust stats
