Quick Reduction of ESI Data Using ESIRedux

As part of the ESIRedux package, there is a routine designed to quickly reduce echellette data using archived calibrations. A fully reduced
1D spectrum is produced in ~8 min of time on the Keck machines. Assuming all of the paths have been properly setup on the esi account
(specifically IDL_PATH, XIDL_DIR, IDLUTILS_DIR, IDLSPEC2D_DIR, ESI_CALIBS), one takes the following steps:

  1. Choose a machine with ~1G of RAM
  2. Set these paths

  3. Launch IDL 5.4

  4. Run esi_echqckrdx:

    esi_echqckrdx, 'filename'

Options:

  1. /CHK will give some graphical output along the way
  2. ARCFIL= will specify the arc
  3. FLATFIL= will specify the flat
  4. REFORDR= will choose the order to find the object in
  5. REFWV= (2 element array specifying wavelength range to identify
  6. SCICLM= Offset of Object from Slit center. If the program stops in esi_echfndobj, the chances are your object is more than 20 pixels away from the defined slit center. Try rerunning with SCICLM=20 the object in)
