Revision as of 01:46, 11 June 2012
Computer OSes
- May 27: Debian Lenny source packages were moved to archive.debian.org. FB updated the packages to reflect this.
- May 27: aptitude on wolverine found more than 65535 (16bit limit) packages to update, causing a bug. FB updated the apt cache size, then updated the distribution source by source.
- May 27: current status = we have the final versions of all Debian Lenny packages (gcc 4.3.2, python 2.5.2, pygtk 2.12.1, gtk 2.12.12)
- May 28: also upgraded lothlorien to ease work on CHAMP
CHAMP -- hardware
- May 26: Larry started pumping CHAMP
- May 27: vacuum ~ 2e-3
- May 28: vacuum reached 1.0e-3, so not quite ready for pumping.
- May 29: CHAMP cool, pressure ~7e-7
- May 29: Despite attempts to reproduce hardware crashes/freezes from last run, none have happened so far.
CHAMP -- software
- May 28: fixed CVS that had been erased from ctrscrut due to a HDD failure in Jan/Feb. Fixed all memory leaks on spooler and astropci reported by cppcheck, especially realloc issues. Reintroduced star info and uv info to spooler, hopefully compatible with CHARA libraries (tests TBD).
- May 29: worked on spooler code, now fully functional, i.e. star + uv info (though this uses partially the old method). Tried unsuccessfully to reproduce the "negative ftnum bug".
- May 30: cleaned up a lot of the python code and debug of automatic calibration -- would need consecutive spots to fully try.
- May 31: continued Pico automatic calibration and automatic spiral search. Spot detection routine not robust yet but spiral search works on single spot. Made backup of code + added to CVS the new spooler code.
- Jun 1-2 : been working on the aligment GUI, fixed many bugs, see
https://www.astro.lsa.umich.edu/intra/research/monnier/internal/index.php/CHAMP_bugs_to_fix
Final final cophasing of MIRC+CHAMP with CHARA
Work on June 10, 2012 (JDM/XC)

Prep: Homing RETRO
BEAM 5-6
MIRC Quality Control checks
Beam 5: 66 cts peak / 732 cts, FWHM 7.6 mu (Fluxes here are xchan / fringe quad)
Beam 6: 51 cts peak / 642 cts, FWHM 7.1 mu
FRINGES (VIS~90%, very little dispersion):
ir5 67750, ir 6 87750, retro 4.723.
Goal: FIX IR6 87750, RETRO 5.720mm, adjust IR5: 55250 (CALIBRATION: 12.5 microns IR% per 10 microns of RETRO)
CHAMP alignment:
Beam5 image quality is great.
Beam5 R6 comment says "image clean" but actually two spots. I will choose bottom one (top one seems to lead to failure)
Beam6 L6 image looks very elongated... vignetting? ugh.
Looking for fringes... FOUND: champ IR5 136685, RETRO 5.720
BEAM 4-5
MIRC Quality Control checck
Beam 4: 85 cts peak / 950 cts, FWHM 6.7 mu (Fluxes here are xchan / fringe quad)
Beam 5: 75 cts peak / 860 cts, FWHM 6.6 mu
Fringes (vis ~ 70%, detectable but small dispersion)!: MIRC-IR4: 84450, RETRO 5.841
CHAMP Alignment:
Problems getting all spots to overlap. It hink the soluiont was to choose different spot for B5 R5... champ ir4: 146754, RETRO 5.841

BEAM 3-4
Nightly Log
- UT June 8, 2012
got lab fringes on beams 1,2
got sky fringes on beams 1,2 (w1-s2).
mirc found fringes with S2 at 5.8mm, we had to move s2 to 7.1mm, so a change of 1.3mm (hmmmm?)
but we tooks some data 2012Jun08/champ0001-0002 and later background files.
