VEGA+MIRC

UT 20:48 = LT 19:48

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

(Ref: W2)

LT 20:00 (HD205021 = Beta Cep) doing fiber alignment
LT 20:45 problem that the cpeak-values are all zero, so gdtControl does not show the right offsts.
LT 21:35 found cross fringe E2 (1.220) - W1 (1.737)
LT 21:45 found E1=3.950, E2=3.185, W1=3.685, W2=0.0, recording data
   	 VEGA also has fringes, slightly offset
	 MIRC ealing mount position (before cophasing with VEGA):
	 IR1=40350, IR2=80449, IR3=66000, IR4=80000
	 MIRC ealing mount position after cophasing:
	 IR1=58350, IR2=65449, IR3=66000, IR4=71600
LT 22:20 VEGA has all fringes, VEGA recordes 4T data, two pairs of 3T data
   	 good seeing
LT 23:20 (HD192907 = Kap Cep) calibrator
   	 recording VEGA+MIRC data
LT 00:20 (HD7034) calibrator
   	 star is above 86 deg elevation, so does not work
LT 00:35 (HD14055 = Gam Tri) target
   	 VEGA does recenter the pupil, we adjust with fiber explorer
LT 01:20 lost W1, reacquire to do shutter 
   	 (we are losing W1, so we change the shutter sequence, 
	 but we lose the star before the required shutter is done)
LT 01:35 (HD7034) calibrator
   	 W1 is out of delay, so we are observing on E1-E2-W2 only
	 recording VEGA+MIRC data on E1-E2-W2
LT 02:10 (HD29248) calibrator for T1OriC, UD=0.27 mas
   	 doing shutter first since VEGA is setting things up
LT 02:42 VEGA is recording one file without tracking (reject in data reduction)
LT 02:47 tracking now with MIRC
   	 recording more shutter data, lost E1 during the shutter sequence
	 took more E1 shutter data
LT 03:10 (HD37022 = Theta1 Ori C) target
   	 recording data (seeing good 8ms)
	 VEGA records 3T-data on triangle E1-W2-W1
LT 03:50 (HD29248) calibrator
   	 out of delay on E1
	 recording data on 3T
LT 04:35 (HD37022 = Theta1 Ori C) target
   	 recording data with 4T
	 VEGA E2-W2-W1
LT 04:55 (HD41547) calibrator H=5.0, V=5.9, faint side for MIRC
	 using flatfield (make sure no fringe there; put coherent coadds=600, Save Number=10000)
	 finding fringes, but it is difficult to see
	 E1 is out of delay, recording 3T data only
	 VEGA E2-W2-W1
LT 05:38 (HD48682) calibrator
   	 recording 3T data (W1 missing)
   	 recording 4T data (W1 found)
   	 VEGA records E1-E2-W2
LT 06:10 (HD40312) target
   	 recording 3T data (W1 missing)
   	 VEGA records E1-E2-W2
