TEL       S2-E2-W1-W2
POP       1-5-1-5
BEAM      B1-B2-B3-B4
TRIPLET   S2-E2-W1  (start-up)

REF CART  E2


LT 21:02 = UT 04:02 = LST 13:16

LT 21:26 - HD152153 (K=3.4)
LT 23:20   recording data, offsets: S2E2=1.816 cm, W1E2=-0.894 cm
   	   the power spektrum shows fringe spikes, 
	   but also some weaker spurious peaks (correlated noise?)
	   NORM readout mode (i.e. reset pixel after each readout), 750 Hz
LT 23:38 - HD192985 (K=4.8)
	   SYNC readout mode (i.e. accumulate flux and reset after each scan), 500 Hz does saturate
	   saturation can be avoided with fastest read-out
LT 00:58   recording 500 frames, NORM readout, 750 Hz
   	   r_0=6-10 cm
LT 01:10 - WR140 
LT 01:30 - HD192985
  	   reference cart was moved, have to do calibrator again
LT 01:45 - HD192985
	   visibility seems to be higher now, maybe better alignment?
LT 02:10 - WR140
LT 02:28 - HD197950
   	   fringes difficult to find due to GPS clock problem
LT 03:20   recording fringes
LT 03:30 - MWC361
   	   recording fringes
LT 03:40 - HD205776
LT 04:20   still cannot find fringes
   	   computer crashed, so have to recover
           running out of delay line, have to give up on this one
LT 04:35 - HD214279 (K=6.0)
   	   recording NORM mode, 500 Hz
	   switching to SYNC, but it is still saturating with 500 Hz!
	   recording SYNC mode, 750 Hz works, but with other frequency, unfortunately
LT 05:15 - closing up
