To All Interested Parties:

A set of IRAF exercises is available for the novice user.  The exercises
have been developed under IRAF Version 2.10.2.  The exercises are complete
with datasets.  Exercises 2 and 4 share the same dataset; 2 reduces the data
that is then used in 4.  Exercises 3 and 5 also share the same dataset; 3
must be executed before 5.  An image display is necessary for exercises 1 and
4, but is optional for the others.  

   1) intro  - an introduction to the basics of IRAF
  
   2) ccd1   - a look at CCD reductions for direct images

   3) ccd2   - CCD reductions for spectroscopic data

   4) phot   - an introduction to aperture photometry using APPHOT and the
               steps for photometric calibration using PHOTCAL

   5) spec   - the extraction and wavelength calibration of slit spectra from
               2-d CCD images

   6) dataio - an exercise in reading and writing tapes

The exercises are available from the IRAF network archive as a compressed
tar file.   The exercises assume that you have unpacked this file in your
IRAF login directory. 

      % ftp iraf.noao.edu (140.252.1.1)

   ftp> quit
      % zcat exer2102.tar.Z | tar -xf -

The exercise instructions are in the exercise/docs directory, in both
text and PostScript format.  The exercises assume one is using xterm and
SAOimage but gterm and imtool will work equally as well.  The m92.ps file
contains a chart of the field for M92 that is used in Exercise 4.  The
spec.eps file contains a chart for identifying thorium lines for the
wavelength calibration in Exercise 5.
