Error - Unable to compute noise estimate
« on: 2016 October 03 14:26:26 »
Hi Folks,

I have a problem when combining a set of subs of M57.....  I have 14X 3min subs but get an error if using the batch pre-processing script or even just image integration.  I have removed the offending sub but then it just fails on the next one and its always channel 2 as well.  Here is a link to one of the problem subs - https://www.dropbox.com/s/o05nc27nnwq8ipr/_300s_20161002_2224_000000052_c_d_r.xisf?dl=0
The error is below:
