HIRedux Coadding

• The following routines all apply to a single object, i.e. multiple exposures of that object will be reduced together.
• Most of the following routines take the hires structure, and the setup, chip and obj_id tags.

Combining Multiple Exposures
hires_combspec :: Combine multiple exposures of a single object. This will work best if the setup did not change between exposures. It may also work if the setup did change, but be careful. Unless you have fluxed the data you should run with /NOFLUX on. You can increase the aggresiveness of clipping by setting REJSIG=3.
    Example: IDL> hires_combspec, hires, setup, obj_id, chip, [exp_id], [/NOFLUX], [/CHK, /MCHK]
