On the 8th and 9th the pipe going to the bubbler was removed for a short 12 Jan 103414 and 110413 time, and on the 13th, the upper HPD array was removed, which meant that the GE was disconnected from the bubbled for ~ 4 hrs. 13 Jan 083115 and 090113 083414 and 090413 083214 and 090214 083314 and 090314 The movements are not proportional to the shock, i.e. dP/dT but to dP 13 Jan 120115 and 123114 120413 and 123413 120213 and 123214 120213 and 123314 19 Jan 073314 is very dim (causes drop in over all intensity) 20 Jan Pictures at 15:0n and 15:3n are shifted wrt others. Also,over all brightness increaases ~14:30 or 15:00 for all cameras 29 Jan 113313 *********************** shifts in February 2009 *********************** 02 Feb around 12:0n Decrease in intensity of both spots (very small in overall) i.e. they follow eachother. But reference of box 4 stays roughly the same and reflected has a small increase-an artifact of the coarse binning, looking at the fine bins, they do decrease as in all boxes. Box 1 (A side Down) Box 4 (C side Down) Box 2 (A side Up) Box 3 (C side Up) Comments ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 05 Feb 100115 100414 100214 100314 Coordinate shift seen by all cameras. In box 4, shifts in y do not follow eachother. At the same time, there is an increase in the over all intensity, seen by all but box 3. The relative I also change (for box 3 as well) although in box 1 they follow eachother. The coordinate shift is clearly visible by eye in box 1 and 2 but in box 3 and 4, the intensity shift is too strong to see it. 06 Feb 110115 - 113114 110414 - 113413 110214 - 113214 110314 - 113314 Relative intensities shift 133114 - 140114 133414 - 140414 133214 - 140214 133314 - 140314 the shift comes back 160115 a visible by eye shift in coordinates 08 Feb 123114 - 130114 --------------- 123214 - 130214 --------------- Shift in relative intensities 10 Feb -------------- --------------- 133215 - 140215 133316 - 140316 Shifts in relative intensities 140116 - 143116 140415 - 143415 140215 - 143215 140316 - 143315 11 Feb 103116 - 110115 103416 - 110415 103216 - 110215 103315 - 110316 Shifts in relative intensities 12 Feb 103115 - 160115 103414 - 150414 103215 - 160215 103315 - 150315 Shifts in relative intensities 160115 - 163115 150414 - 163414 160215 - 163215 150315 - 163315 Shifts in relative intensities 163215 - 170215 163315 - 170314 Shifts in coordinates aswell The lower HPD box was put back in, so the pressure was releaased. The fibres were disconnected for that purpose and then the C-side fibre was not plugged in properly so box 1 and 2 have lost a few pictures more than 3 and 4 13 Feb -------------- 100415 - 103415 --------------- 100315 - 103315 Shifts in relative intensities 103115 - 110116 --------------- 103215 - 110215 --------------- --------------- --------------- 110215 - 113215 110315 - 113315 --------------- 113415 - 120415 --------------- 113315 - 120315 --------------------------------------------------------------------------------------------------------------------------------- 09 to 15 May 2009 cam00 and cam03 see large shift in reflected spots 15 to 16 May 2009 cam01 and cam02 see large shift in reflected spots
