NIKA October 17th, 2015 / S8

Back to list of day to day logbook of observations

2015-10-17

Following not updated

The sky is populated with thick dark clouds, but there is a forecast of a clear patch from 9:30 to noon.

Set Focus : we start at 0.0 mm We updated ini.pako. Remember 1mm difference between the focus of NIKA and the focus of the other IRAM instruments due to the design of the optics (SL).

Quick description of the session: focus tests.

113	10h03	Jupiter	Beammap (1/3)	195	59	2.1,0.7,0.2	0.77	Jupiter is just 30' from Mars, with a nice distribution of its satellites: it's too tempting, just for the fun of the picture! CANCELLED: Map too small.
114	10h13	Jupiter	OTFgeom_20am	195	59	2.1,0.7,0.2	0.67	Setting scan to map Jupiter with its satellites (1200" x 240"). 14: realized we got the wrong direction of offset: Azimuth increase right to left in Xephem, not left to right !!!!
115	10h41		Skidip	206		2.1,0.7,0.2	0.70
116	10h50		Skidip	206		2.1,0.7,0.2	0.69	weather not so good, do some skydip stat, while looking for the right test scripts on Jupiter's satellites

119	11h14	Ganymede	nkotf	206	45	2.1,0.7,0.2	0.69	Testing nkotf script, first in AZ-EL. Trying to get Ganymede, Callisto, and Europa in one map. CANCELED! Many telescope alarms switched on. Stop. Juan Luis restarted the system. Then wind too high.
120	12h21	Mars	Track	242	41	0.0,0.0,0.	0.71	Relaunch PaKo, Back on track
121	12h23	Mars	Pointcross	242	41	0.0,0.0,0.	0.71	Same problem as each time we start PaKo while NIKA Control is already running: desynchronized scan. Restart all NIKA control instruments.
122	12h34	Mars	Pointcross	242	41	0.0,0.0,0.	0.71	High opacity, High wind...
123	12h41	Mars	Focus	242	41	-2.6,-2.6,0.	0.71	quite noisy, redo to check
124	12h47	Mars	Focus	242	41	-2.6,-2.6,0.3	0.71	even worse, untrusty
125	12h50	Mars	Pointcross	242	41	-2.6,-2.6,0.3	0.71
126	12h55	Mars	Focus	247	37	-0.5,-3.4,0.3	0.71	OK, a bit less noisy, big error bars but confirm previous scan
127	13h00	Ganymede	track	250	35	-0.5,-3.4,0.3	0.69	Trying to get Ganymede, Callisto, and Europa in one map. Testing script + map with objects showing an orientation. NCS crashed
127	13h18	Ganymede	track	250	35	-0.5,-3.4,0.3	0.69	NCS crashed
129	13h25	Ganymede	track	250	35	-0.5,-3.4,0.3	0.69	NCS crashed
130	13h25	Ganymede	track	250	35	-0.5,-3.4,0.3	0.69	NCS crashed
131	13h25	Ganymede	track	250	35	-0.5,-3.4,0.3	0.69	NCS crashed. Juan Luis and Israel working on it.
133	13h25	Ganymede	track	250	35	-0.5,-3.4,0.3	0.69	NCS crashed. Apparently the problem is Ganymede: NCS doesn't know how to track a planet's satellite !!!
134	14h00	Jupiter	track	250	35	-0.5,-3.4,0.3	0.69	Now it works. Looks like Ganymede was indeed the problem !
135	14h10	Jupiter	OTFgeom_20am	195	59	2.1,0.7,0.2	0.67	Jupiter too low to make the nkotf test. the time to find another triple source redo OTF (1200" x 240"). Cancelled: wrong direction of offset, Azimuth increase right to left in Xephem, not left to right !!!!
136	14h20	Jupiter	OTFgeom_20am	195	59	2.1,0.7,0.2	0.67	Now OTF (1200" x 240") with the right offset.
