I used ASI Studio for taking some flats and the metafile info is incorrect which prevented me to integrate under APP.
I included a view and the file itself. Issue is:
File info: Flat_M63_6sec_Bin2_2020-05-22_123706_frame0015_ 33.1C_gain100
Pixel width (XPIXSZ & YPIXSZ)after binning is incorrect: it shows the native 3.76 when it should be 7.52 (x2) as BIN2.
Length of data axis 1 (NAXIS1) shows 3120 but should be 3124 (6248/2)
I've basically wasted 2 days of amazing data gathering because the BIN 2 column conversion from ZWO is missing 4 columns on my Flats. (3120 on the Y axis - height when it should be 3124) Frustrating to say the least. Doent matter if I try Pixinsight or APP. They just wont use these flats as the "geometry" is not the same. (3124 versus 2120)
