I have some data from CTIO with AMPLIST

But some of them are AMPLIST 22 OG 530

Thanks!

about the flux calibration of a spectrumStarted by:haha, 09/04/2014 03:49AM
when we run
apall

Automatically there is a size for an
aperture. That size is the FWHM or
something of the aperture? Or we can
choose the size of the aperture by
ourself?

If we choose by hand, the flux may
become arbitrary?
