TAPAS is working properly

Data Repository: /home/nika2/NIKA/Data/run13_X/scan24_X

Goal of the session:

OTF geometry and beam map on Uranus
check pointing on faint sources (pako pointing f and pointing l)

Scan	UT	Source	Command	Az	El	Pointing X, Y, Focus	Tau225	Comment
12		Uranus	track			0 0 0	0.39	We are not as good as Martino. took us 25 minutes to get the resonances...
13	01h37	Uranus	skydip_DIY			0 0 0		resonances well peaked after the skydip. auto_nika_rta tries to reduce skydip and fails.
14	01h40	Uranus	track	236	44	0 0 0
15	01h40	Uranus	nkpoint b	236	44	0 0 0	0.46	good fit. set pointing 0.3 0.8. FWHM = 14"@1mm, 19"@2mm
16	01h42	Uranus	focustrack z	237	44	0.3, 0.8 , 0.	0.46	not a great fit. set focus -0.42 and do it again.
17	01h48	Uranus	focustrack z	237	44	0.3, 0.8 , -0. 42	0.45	better fit. set focus -0.35
18	01h50	Uranus	focustrack x	239	43	0.3, 0.8 , -0.35	0.46	good fit. set focus -0.32 /dir X . large change, do it again to check
19	01h56	Uranus	focustrack x	239	42	0.3, 0.8 , -0.35	0.46	good fit. set focus /dir X -0.83 Large change !!! try Y and set nsubscan to 9 from scan 21 onward
20	02h03	Uranus	focustrack y	241	41	0.3, 0.8 , -0.35	0.46	good fit. set focus 0.29 /dir Y. large change, do it again to check
21	02h04	Uranus	focustrack y	242	40	0.3, 0.8 , -0.35	0.46	not a good fit, no solution @ 2mm. Do a pointing to check beam shape
22	02h10	Uranus	nkpoint b	243	40	0.3, 0.8 , -0.35	0.46	set pointing -0.5 1, beam is 13" - 18" and looks more circular
23	02h10	Uranus	beammap	243	39	0.3, 0.8 , -0.35	0.46	Scan cancelled, forgot to update pointing before lauching
24-26	02h15	Uranus	beammap	244	36	-0.5, 1.0, -0.35	0.2-0.79	resonances fine at the start of first, second and third scan. tau 225 unstable during map
27	02h	Uranus	nkpoint b	252	20	0.3, 0.8 , -0.35	0.46	check pointing after beammap. set pointing -0.6 -0.3 . beam looks larger. 13" and 20"
28	03h01	Uranus	skydip_DIY	252		-0.6, -0.3, -0.35	0.44	resonances well peaked after the skydip. auto_nika_rta tries to reduce skydip and fails. Uranus getting low, will check focus on 3C84
29	03h08	3C84	track	290	70	-0.6, -0.3, -0.35	0.41
30	03h11	3C84	nkpoint b	290	70	-0.6, -0.3, -0.35	0.41	set pointing 5.9, 0.7. does not look too good, will try point faint
31	03h15	3C84	nkpoint f	290	69	5.9, 0.7, -0.35	0.61	auto_nk_rta cannot reduce the pointing. neglect corrections. try point liss.
32	03h20	3C84	nkpoint l	290	68	5.9, 0.7, -0.35	0.96	set pointing 5.0 1.2. FWHM 12 and 18" will try to focus...
33	03h26	3C84	focustrack z	289	67	5.0, 1.2, -0.35	0.43	tau very unstable... set focus -0.04 set nsubscans to 10
34	03h30	3C84	focustrack z	289	67	5.0, 1.2, -0.04	0.43	tau very unstable... do not help having a good fit without opacity correction set focus 0.00 set subscan to 12
35	03h38	3C84	focustrack x	289	64	5.0, 1.2, -0.00	0.43	set focus -0.77 /dir X opacity variation not helping
36	03h45	3C84	focustrack y	289	64	5.0, 1.2, -0.00	0.43	good fit. set focus 0.13 /dir Y small move since last time redo a point liss to check beam shape.
37	03h52	3C84	nkpoint l	290	61	5.0, 1.2, -0.00	0.42	set pointing 3.7, 1.9. Beam does not look great or is it the source ?
