UT 2010-10-14
=============

VEGA+MIRC

UT 20:48 = LT 19:48

start with
B1-B2-B3-B4
E1-E2-W2-W1

POPs:
S1-S2-E1-E2-W1-W2
 4- 5- 1- 2- 1- 5

(Ref: W2)

LT 19:15 (HD195725) calibrator, doing fiber alignment
   	 recording MIRC+VEGA, good seeing, fringes very nice and clear
LT 20:00 (HD205021 = Beta Cep)
   	 recording MIRC+VEGA
LT 20:40 (HD195725) calibrator
   	 recording MIRC+VEGA
LT 21:00 (HD205021 = Beta Cep)
   	 recording MIRC+VEGA
LT 21:33 (HD195725) calibrator
   	 recording MIRC+VEGA
LT 22:17 (HD205021 = Beta Cep)
   	 recording MIRC+VEGA

LT 23:25 switching to:
         B1-B2-B3-B4
         S1-S2-W2-W1  (VEGA config: S1-S2-W2, S2-W2-W1)
LT 00:00 cannot find fringes
   	 problem with LDCs
	 have to reboot OPLE
	 OPLE crashes astropci
	 astropci restarted, freezes OPLE
	 have to reboot OPLE
LT 02:15 (HD29248) calibrator
   	 still good seeing, but worse than at beginning of the night
	 find 3 fringes, but W2-W1 does not appear
	 likely problem with LDCs again
	 cannot find fringes on W1 with MIRC, although they appear on VEGA
	 compared to the configuration E1E2W2W1, the internal offset has clearly changed
	 (maybe due to differences in the LDC on S2, which introduces
	 a different chromatic OPD for the different configurations)
LT 03:20 therefore record 3T-data on S1-S2-W2 (W1 missing)
LT 03:55 (HD37022) target
   	 find W1 precisely at expected position
	 recording data (MIRC 4T, VEGA S1S2W2)
	 fringes much more stable than yesterday, good seeing
	 recording data (MIRC 4T, VEGA S2W2W1)
	 seeing 5-18cm
LT 04:46 (HD29248) calibrator
   	 recording data (MIRC 4T, VEGA S2W2W1)
	 running out of delay for 4T, continue 3T to calibrate VEGA data
   	 recording data (MIRC 3T, VEGA S1S2W2)
LT 05:20 (HD37022) target
   	 recording data (MIRC 4T, VEGA S2W2W1), medium tracking quality
	 fringes move much more than on the visit before
	 running out of delay on W1
	 recording data (MIRC 3T, VEGA S1S2W2), very poor tracking quality (likely useless)
	 spooler crashed when W1 got lost, crashed again when I try to restart
	 after a few minutes, it's possible to restart spooler
LT 06:33 (HD43023) bright calibrator for MIRC
   	 during twilight
	 recording data (4T MIRC, VEGA also tries recording)
	 for a few frames, there are all 4 fringes
	 lost W1 due to twilight
	 doing shutter
LT 06:44 closing
