TODO LIST

• Recenter champ internal mirrors while maintaining CHARA internal fringes and also keep MIRC fringes.

• Focus champ ToP mirrors.

• Start working on the automatic alignment

2011July JDM Notes

2011 1 July

FB: mainly worked on integrating CHAMP with chara system, which requires solving some dependencies and conflicts. This is not an easy task as a lot of the code has been duplicated into files specific to CHAMP. Vacuum pumped CHAMP in prevision for the run, pressure ~5e-6.

2011 2-3 July

FB: Went to get Xiao at the airport. Still working on the code, most of it compiles but still many issues, need to make the error() functions from CHAMP and CHARA compatible, as well as the char_waiting() function. CHAMP now cooled, pressure is high ~1.5e-6 but lots of outgassing from the inner dewar so will see when stabilized.

2011 4 July

FB: astropci_usr now compiles without errors as a CHARA server, need to check everything works.Did the internal alignment for CHAMP. Pressure is dropping, 1e-6 at the end of the day.

2011 5 July

FB: test if camera/pyramid are well aligned, more work on CHARA servers.

2011 6 July

Started working on automatic alignment.

2011 7 July

Clock issues between MIRC and CHAMP.
