I was attempting to plot spectral index vs. an L-Band flux using the task IMVIM today. The index of the AIPS cookbook (15-Apr-1999) gives pages 6-11, and 6-13 as cited pages. The task IMVIM does not appear in text on either of these pages. Where might I be able to find how to utilize this task? Thank you for your time. Sincerely, Jared Paul Helston
