# DEIMOS flexure compensation look up table # Created June 18, 2002, Shui Hung Kwok # # This file complies with the naming convention: # camera_name + underscore + "flex.lut". # Must be located in $KROOT/rel/default/data or ~/qfix. # # Content: # The columns in the table are: # (1) ROTPPOSN mod 360 [deg] # (2) Uncorrected X position of fiducial on guider [px] # (3) Uncorrected Y position of fiducial on guider [px] # # Note: # ROTPPOSN values should lie in the range 0 <= x < 360; software # will properly interpolate using the 0 degree data for 360. # # The data below represent the position of a fiducial mark # on the DEIMOS guider during rotation. They are currently the # average of the positions observed during forward and reverse motion, # which have separate curves. # # These data represent the output of the IDL program # /home/dmoseng/idl/dmsoeng/T953_plot.pro. # # Please see instructions posted at: # http://www.keck.hawaii.edu/realpublic/inst/deimos/T953.html # # Example: # 0 1 2 # 20 3 4 # 60 5 6 # 90 7 8 # 180 9 10 # 270 0 0 # # Modification history: # 2002-Jun-18 GDW Original version based on flexure # measurements made on 2002-Jun-14 # 2002-Jul-03 GDW Revised following modifications to the # DEIMOS guider mount and subsequent # remeasurement # 2002-Sep-26 GDW Revised following Aug 2002 repair of # TV guider system # 2008-Jun-11 GDW Recomputed flexure prior to on-sky # testing for MAGIQ #----------------------------------------------------------------------- # Put your data here: # ROTPPOSN Xpos Ypos #----------------------------------------------------------------------- # ROTPPO X Y 10 513.04 640.87 40 512.51 640.08 70 512.09 638.99 100 511.94 638.54 130 512.05 638.16 160 512.46 638.58 190 513.05 639.08 220 513.66 639.98 250 513.95 640.99 280 514.07 641.40 310 513.92 641.76 340 513.59 641.77
