Rather than present a lot of text here, I'll just give links to detailed (and verbose!) discussions of reductions made after various engineering runs. I also provide a figure that summaries the running of find_ihmp_on_acm, the tool I use to evaluate new values for the shuffle.cf paramaters: acam_x_origin, acam_y_origin.

  1. Running find_acm_on_ihmp on 20180929 UT data
  2. Running find_acm_on_ihmp on 20180727 UT data
  3. Running find_acm_on_ihmp on Dec2017 data


The IHMP to acm fit made with the positions (acm coordinate frame in pixel units) for 056 (LRS2-B), 066(LRS2-R), 555(BIB), and 600(HPFacq). In this case the small blue squares are the original acm positions. The larger red squares are the IHMP positions transformed to the acm system using the results from our trs_solve_2 run. These results are contained in the local file named TRS.final. Below are the (1) input file to the processing script find_ihmp_on_acm, (2) the command line call to make the run, and (3) the new acm parameters for shuffle: 

% cat Data.ALL                # the input data file 
# IHMP-acm positions after Jul2018 FPA take-down
# name     X,Y_ihmp       X,Y_acm
# data
555       3.3  -73.2    448.5  402.2
600     -35.0   10.1    140.8  257.7
056     -49.8 -148.7    731.6  212.0
066      49.8 -151.3    734.5  582.0
% find_ihmp_on_acm Data.ALL   # the command line 
 # New shuffle parameters 
  acam_x_origin =  179.3  -+1.8    (units of acm pixels)    
  acam_y_origin =  385.4  -+1.4    (units of acm pixels)
