Tutorial setup, data & directories

• Make sure you have Anaconda installed, with the necessary Astroconda packages, as described at http://www.gemini.edu/node/12665.

• Make sure your shell session is configured to use the conda environment into which you installed the Astroconda packages (eg. “gemini” or “astroconda”):

  > source activate <env>
  

• Unpack the data tarball somewhere under your home directory (producing a subdirectory of the same name).

  > tar zxf GMOS_IFU_2017.tar.gz
  > cd GMOS_IFU_tut_2017/
  

• Copy LA Cosmic (from http://www.astro.yale.edu/dokkum/lacosmic/lacos_spec.cl) into the scripts/ subdirectory.

• Create an IRAF login.cl in the red/ subdirectory:

  > cd red/
  > mkiraf
  

  (Answer xterm or xgterm for the terminal type, not xterm-256color.)

• The directories are structured as follows:

  raw/	All of the raw FITS files needed for the tutorial
  red/	Working directory for reducing data
  scripts/	Reduction scripts and look-up tables
