Description
A bright satellite streak may be identified as a CR by psphot, making them more difficult to detect.
There are also pixels on the edge of cells which are masked as CRs.

We agreed that the best thing to do is to identify and flag sources on a satellite streak using a line detection algorithm; such sources should be excluded from the CR masking so the streaks can be found by magic.
Note:
See TracTickets
for help on using tickets.
Pixels on the edge masked as CRs were due to bad dark pixels having mask set to "maskValue", which includes CR; then these pixels were grown (setting to CR) by psphot. This part has been fixed on trunk, r24079.
