Dirty results from batch pre process: What is this stuff?
« on: 2014 June 04 15:03:18 »
Hi All:

I've been away from PI for a bit. My recent processing of M16 leaves me perplexed. The batch preprocesser returns results that contain "dirt" not in the subs. Please see attached.
What have I done wrong?

check the calibrated subs, the calibration is probably bad…

Thanks, pfile.

I changed from Winsorized Sigma to Sigma in the integration tool and the "dirt" went away.

ok i think that means then that the rejection parameters were rejecting too many pixels… how many subs do you have?

Fifteen 10-minute subs each in R, G and B.
