Following not updated

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
if time check Neptune
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	241	41	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	241	44	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	44	0.3, 0.8 , -0.35	0.46	Scan cancelled, forgot to uopdate pointing before lauchin
24-26	02h15	Uranus	beammap	244	38	-0.5, 1.0, -0.35	0.	resonances fine at the start.
