arc/standard star/object comsbination problem

haha wrote on Jul 10, 2015

Hi all,

If there are two different exposures along two different columns for one object, one has to process them independently, and at last combine the two spectra to remove cosmic rays?

If arc lines are taken independently, for example, He/Ne/Ar are taken one by one, one needs to combine them first to identify lines using one file? Or one can run 'identify' many times? In the second scenario, in the database, there are multiple identification files.

How to combine standard star/object files if they have different exposure times?
