<p>141.213.168.87: </p> <hr /> <div>== Computer OSes ==<br /> <br /> * May 27: Debian Lenny source packages were moved to archive.debian.org. FB updated the packages to reflect this. <br /> <br /> * 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.<br /> <br /> * 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)<br /> <br /> * May 28: also upgraded lothlorien to ease work on CHAMP<br /> <br /> == CHAMP -- hardware ==<br /> <br /> * May 26: Larry started pumping CHAMP<br /> <br /> * May 27: vacuum ~ 2e-3<br /> <br /> * May 28: vacuum reached 1.0e-3, so not quite ready for pumping. <br /> <br /> * May 29: CHAMP cool, pressure ~7e-7<br /> <br /> * May 29: Despite attempts to reproduce hardware crashes/freezes from last run, none have happened so far. <br /> <br /> == CHAMP -- software ==<br /> <br /> * 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).<br /> <br /> * 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 &quot;negative ftnum bug&quot;. <br /> <br /> * May 30: cleaned up a lot of the python code and debug of automatic calibration -- would need consecutive spots to fully try.<br /> <br /> * 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.<br /> <br /> * Jun 1-2 : been working on the aligment GUI, fixed many bugs, see<br /> https://www.astro.lsa.umich.edu/intra/research/monnier/internal/index.php/CHAMP_bugs_to_fix<br /> <br /> <br /> == Nightly Log ==<br /> <br /> *UT June 8, 2012<br /> <br /> got lab fringes on beams 1,2<br /> <br /> got sky fringes on beams 1,2 (w1-s2).<br /> <br /> mirc found fringes with S2 at 5.8mm, we had to move s2 to 7.1mm, so a change of 1.3mm (hmmmm?)<br /> <br /> but we tooks some data 2012Jun08/champ0001-0002 and later background files.</div>
