This is a revised version of lmap, a code used for viewing LRS2 spectra and the corresponding spatial image from a single LRS2 channel for a given observation (obs) and exposure (exp). It may be useful to read a deatiled description of building spatial images with lmap. The improvements available in this markII version are wavelegth calibaration and extraction of a full spectrum for each fiber in the IFU.

% 
% lmap_markII -h 
usage: lmap_markII 32 2 or [-v] [-h]  
arg1 = observation value 
arg2 = exposure number 
arg3 = channel name (uv,or,rd,fr)
Additional options: 
  -h = just show usage message  
  -v = run in verbose/debug mode 

=================================
I have two examples of runs: 

NOTE: If you run on mcs, the BaseDir file will always contain:   /hetdata/data

This lmap version can trace each fiber spectrum to integrate signal for the spatial map. I also installed some simple wavelength calibration capabilities.
