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 *** Target summary: WR 140 UT2010Jun07 S2-E2-W1 good quality UT2010Jun07 S2-E2-W1 good quality MWC 361 UT2010Jun07 S2-E2-W1 good quality, could not complete full sequence
