Summary

Did not open for dust, and later, high winds.

Tested machinery for collecting transform data.

  • Doug tested his IDL script and that it could take MODS2 images using a Unix shell interface command (mods2Cmd) provided by Rick
  • Rick provided a support script to configure the instrument in preparation for taking transform data.
    • ~modseng/modsScripts/Support/transformInit.pro
      • Configures instrument in red-only imaging mode, including an explicit imcslock (required for a low-level script like this)
      • ROI: 1K x 1K with 1x1 binning
      • Opens the hatch and resets the AGw stage, retracts any slit mask that might be installed.
    • Before taking transform data:
      • execMODS2 modsWake.pro
      • execMODS2 transformInit.pro
      • make sure the filename is set correctly for the UTC date

Note that for MODS2 the command "execMODS2" is provided. A common execMODS/acqMODS/etc. will be tested during MODS2 commissioning
and released only after MODS2 is released for partner observing.

Creating new Stone catalogs:

for collection of transform data

Created catalogs for several Stone fields that were optimized to have many stars within the MODS2 5' x 5' guider patrol field. These catalogs are in /home/lbto/idl/catalogs/Stone/ and may be in svn now. Positions, finding charts and lists for these fields are in, /home/lbto/MODS2Comm/StoneFields. The table below lists a Reference Name, RA,DEC of catalog center, Catalog Name and the finding charts created by modsView (MODS imaging scripts, created to visualize the field, are also in this directory, a screen shot of the output of IDL program used to select these fields (do_nn.pro) and the do_nn.pro calling arguments and resultant list of Stone stars. NB: The field center output by do_nn is the center of the patrol field. The catalog center is along one of the edges, and the PA = 0,90,180 or 270 was chosen accordingly.

for astrometry (scale and rotation) of guide camera CCD

Created catalogs for several regions within Stone M that had a relatively high density of stars within the 40" x 40" guide camera FOV, and may be suitable for guide camera astrometry. Of these 3 fields, Mdns2 is the best one, containing stars of a range of magnitudes and well-distributed over the field. These fields each have 7 Stone stars. Denser fields would still be better (such as those in M92).
