Here we have use lmap to view the red channel in a set of LRS2 data with obs=008 and exp=01 with the command: % lmap 008 01 rd N The two red channel images are shown in the two left panels. The LRS2 spatial reconstruction is in the upper-right, and the acm view is in the lower-right. Note that the green circles were draw by the user to measure the locations of the star in the IFU and acm coordinate systems. For completenes I show the BaseDir and Date files I used: % cat BaseDir /home/sco/HET_work/finding_charts % cat Date 20170209

 
 
Local LRS2 image = lrs2map.fits
Acam image       = 20170209T050520.4_acm_sci.fits
501.00 270.71            X,Y (in pixels) from map 
725.64 571.67          X,Y (in pixels) from acam
 -0.162250 0.216972      X,Y (in  arcsec) from LRS2 map 
008 01 rd 20170209     (obs,exp,channel,date)

Based on the LRS2 image, here is your correction to center the target: 
mgp -toff=-0.162250,-0.216972

   501.00  270.71    725.64  571.67  -0.1623  0.2170   008  01  rd  20170209    20170209T050520.4_acm_sci.fits 

The lmap code is not really deprecated, but a more advanced version worth looking at is lmap_markII. In preparation for this upgrade, I wrote a detailed software review of lmap. It may be useful to read a deatiled description of building spatial images with lmap.

View LRS2 spectra and the corresponding spatial image from a single channel for a given observation (obs) and exposure (exp). This code MUST be run in a location that is separate from the original raw data directory (usually /hetdata/data/YYYYMMDD). The local files BaseDir and Date can be used to specifiy the base directory (usually /hetdata/data on mcs) and the date (i.e. 20160816). If these files do not exist in the local directory, the user will be queried for them.

% 
% lmap
Usage: lmap 009 05 or N
arg1 = observation value (3 chars, e.g. 003)
arg2 = exposure number (2 chars, e.g. 01)
arg3 = channel name (uv,or,rd,fr)
agr4 = run in debug/verbose mode (Y/N)
NOTE: uv=UV or=Orange, rd=Red, fr=Far-Red
 
(The BaseDir and Date files each contain a single line)
% cat BaseDir 
/home/sco/HET_work/finding_charts   # typical path on my home machine 
/hetdata/data                       # typical path on mcs 
% cat Date

1. Oct2018: Speed up the location of matching acm images.
2. Mar2019: Major lmap update.
