Astronomy 830 - Au2003 - Problem Set 2: Spectral Classification

Problem 2 Spectra for Subo Dong

Individual Spectra: mstar1.spc; mstar2.spc; sd1_1.spc; sd1_2.spc; sd1_3.spc
Gzipped TAR file of all spectra: sd1.tgz

The spectra are in 3-column ASCII format as follows:

   pixel   lambda   relflux

where

   pixel   = original pixel number (runs 1-2899 or 2898)
   lambda  = wavelength in Angstroms
   relflux = flux in erg/sec/cm^2/Angstrom relative to the flux at 5500A

For this exercise, you want to plot flux vs. lambda, and then use that plot to identify the lines for classification.
