is belonged to 2MASS All-Sky Catalog of
Point Sources. It can be got at
badc.lamost.org.

Is it a database? How can I use this
catalog?

Moreover, Where can I get the...

a question about spectral analysisStarted by:owen, 03/21/2008 09:47AM
Dear all,

I am faced with a question about
spectral analysis. In order to measure
emission lines, one need to correct
stellar absorption for observed spectra,
or subtract continuum. Can IRAF carry
out this work? Which task may I employ?

Thanks a lot!
