Combining Multiple Exposures
- 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.
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.
