Data reduction
No pipeline support will be provided for the imaging data as there are lots of tools to reduce
imaging data, extract the objects, and do the photometry. Pipeline support will be provided
for the detector linearity determination only. Below are some basic guidelines of imaging data
reduction with IRAF and the swarp software:
0) Preliminary steps
Inspect the images, reject the flat-fields with too many stars or star traces.
Create files listing the frames per type.
Make sure to use darks and flat-fields with the same integration times.
1) Create the masterbias
In IRAF, use the imcombine task to median combine the bias images.
