Notes from etalon run

2015Jun23 (calendar)

Beam 6 was giving us problems.. A highly comatic image. we adjusted the pickoff tip/tilt and the z-position to optimize the flux (increase x2) We now have an excellent image FWHM 7.1 and no coma, although fluxes are still low by x2 compared to best other ones... not sure why.

luminous mounts 6: x,y,z and ealing 56320, 98990, 89053, 60000 compared to original position: 61060, 60750,89153, 87750.

we expect teh RETRO fringes to now be in a different place compared to last time and yesterday.

now we will move to the grism mode.

so we setup camera based on last run: So we had to the 'flip quadrant function.' setup was: 48 252 100 2 4 500 500 which gave frame times of 13ms (Ok)

next we move prism out of the way -- from 505213 -> 0

next talking to filterwheels. turn on mirc and champ filterwheel power from APC webpages.

run script: wolverine2:Subversion/MIRC/MIRC6T/scripts/filterwheel.sh (be patient. this takes a while)

ok.. light was perfectly centered in the above software window.

XCHANS shifted: PRISM: 201 213 219 164 188 176 NOW for R150, quad flip: 199 211 217 162 186 174

RETRO for B5B6 is now 9.9049 (instead of 7.715mm because we shifted the B6 ealing mount by 2.7mm) Now taking fringe data on all pairs, both w/ and w/o etalon. remember to turn tiptilt on for spooler.

taking internal fringe data w/ and w/o etalons.

ok. xchannels shifted by when we switched to new mode.
