NIKA October 15th, 2015 / S1

Back to list of day to day logbook of observations

2015-10-15

Following not updated

.Cryostat Temperature: 170mK cooling down slowly Arrays status tonight: full 2mm array - 1-3 Hz noise; 2 feed lines on 1mm array 3-5Hz noise Modulation frequency: 10kHz 1mm, 5kHz 2mm

For this session Array 3 is connected, but still less stable than the others.

Opacity is measured with the new taumeter at 225 GHz

Nasmyth offsets : 0, 0

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.

Scan	UT	Source	Command	Az	El	Pointing X, Y, Focus	Tau225	Comment
100	07h12	Mars	Track point	124	47	0,0,0.	0.14	Pointing towards Mars. We are using the geometry reduced from yesterday's observation (kidpar_20151015s154_155_156_noskydip.fits)
101	07h18	Mars	Pointingcross	124	47	0,0,0.	0.14	Checking pointing. Problem: All subscans set to 0. But the sze of the file is correct.
102	07h21	Mars	Pointingcross	124	47	0,0,0.	0.14	Checking pointing. Problem: All subscans set to 0. Martino investigating the issue.
103	07h24	Mars	Pointingcross	126	48	0,0,0.	0.14	Checking pointing. Problem: All subscans set to 0.
104	07h33	Mars	Pointingcross	126	48	0,0,0.	0.14	Retrying scan after Martino tweaks codes. Seems to be related to the order in which we launch programs of the NIKA control software.
105	07h38	Mars	Pointingcross	129	50	-8.7,3.3,0.	0.11	Correcting pointing. Comparing with the beam model (SL), the 1mm profile seems consistent with the scan and the diffraction produced by the tetrapod.
106	07h43	Mars	Focustrack	132	51	-8.7,3.3,0.	0.19	Axis=Z. At 1mm: z=-0.028+/-0.009. At 2mm: z=0.058+/-0.042. Close enough, keeping focus Z=0.0
107	07h54	Mars	Focustrack	136	52	-8.7,3.3,0.	0.17	Axis=X. At 1mm: x=-0.079+/-0.021. At 2mm: x=0.188+/-0.289.
108	07h58	Mars	Focustrack	136	52	-8.7,3.3,0.	0.17	Axis=Y. At 1mm: y=-0.018+/-0.037. At 2mm: y=0.044+/-0.67. Difficult to do better in Y.
107	07h54	Mars	Focustrack	136	52	-8.7,3.3,0.	0.17	Axis=X. X focus = 0.1. At 1mm: x=-0.079+/-0.021. At 2mm: x=0.188+/-0.289.
