How to Reduce Inclinometry Data

How to Reduce Inclinometry Data

  • Go into /home/hthomas/inclinometry/
  • Run get_incfile.sh. This asks for the date the inclinometry run was performed.
  • Run create_cw_fileformat.sh on the raw inc file. This splits it into clockwise and counter-clockwise files, reverses the order of the ccw data and adds the appropriate headers.
  • Go to the Hilo computers /home/hthomas/inclinometry/
  • Run scp_from_kolea.sh. This copies the cw and ccw files across for a given date.
  • Run incdisp.exe:
    • Channels TX, LX, RX. Check that these are all similar to each other, have values no more than 1000 units (mV) from zero, and have amplitudes of approximately 400mV. Compare with the example .
    • Channels TY, LY, RY. The TY and RY should be similar this time, and the inverse and 180 degrees out of phase with LY. Again, all data should be within 1000mV of zero and have amplitudes of approx 500mV. Compare with the example .
    • Channels TT, LT, RT. All should read about 100+50.
  • Run the new data as input(s) to rlb.exe.
  • Run cleanup-rlb.sh after each. This renames the files and updates the appropriate log files.
  • Run the corrected (c-) data as input(s) to makemodel.exe. Make a model for both the cw and ccw data.
  • Run cleanup-makemodel.sh.
  • Use meandiff.exe to show the changes between the current cw model and the previous cw model taken at the last inclinometry run. You should expect differences of only an arcsecond, with some small systematic components only.
  • Run meandiff.exe to get the difference between the cw and ccw models.
  • Use make_hybrid.exe. If the ccw data is not available for this run then use a previous cw-ccw file instead.
  • make .gif files of all plots for the report and copy into /web/html/JCMT/telescope/pointing/
  • Copy (scp) the hybrid model into /jac_sw/itsroot/src/tcs/params on the summit computers,
  • Edit the second line to reflect the number of entries (usually 806),
  • Move it to thi_trackmodel.dat
  • source /jac_sw/itsroot/etc/login
  • make (to install)
  • cvs commit -m "(YYYYMMDD -HST -track model update)"
