1-5		Uranus	focusliss	~40	[0,0,-2.4]	0.5	sky variable strange values set focus -1.7 to try
6-10		Uranus	focusliss	~40	[0,0,-1.7]	0.45	again strange, not fitting well set focus -1 to try
11-15		Uranus	focusliss	39	[0,0,-1.0]	0.65	wild sky, not fitting, best FWHM 14 and 20arcsec set focus -0.8
16		Uranus	cross	39	[0,0,-0.8]	0.55	set pointing -4.7 6.4 to go on 1mm ref det
17		Uranus	focus track	39	[-4.7,6.4,-0.8]	0.55	found -0.8 at 1mm and -0.6 at 2mm so perfect !!
18		Uranus	cross	39	[-4.7,6.4,-0.8]	0.61	to check pointing on 1mm NOT WORKED
19		Uranus	cross	39	[-0.5,-1.4,-0.8]	0.61	set pointing -0.5 -1.4 to go on 2mm
20		Uranus	cross	39	[-0.5,-1.4,-0.8]	0.66	strange, find -7 0.5 NICOLAS B. SAYS AFTER DEICING IS SWITCHED OFF ON M2 FOR 2-3 hours CAN DO STRANGE THINGS
21		Uranus	cross	39	[-0.5,-1.4,-0.8]	0.66	strange noise on 1mm ??
22		Uranus	focusZ	39	[-0.5,-1.4,-0.8]	0.66	test new script
23	around 2h	3C84	track	33	[-0.5,-1.4,-0.8]	0.8	go higher in EL since tau is very high

WE STOP FOR TONIGHT, IN THE CLOUDS, TAU=1

24-26	18h15	Uranus	track		36	[0,0,??]	0.3	set focus -1.5
27-31	18h27	Uranus	focusliss		36-40	[0,0,-1.5]	0.3-0.6	time traces varying by 30kHz at 2mm !!
32-36	18h37	Uranus	focusliss		36-40	[0,0,-1.5]	0.2 (!?)	time traces varying by >>10kHz at 2mm !!
37-41	18h46	Uranus	focusliss		36-40	[0,0,-1.5]	0.3 (!?)	time traces varying by >>10kHz at 2mm !!
42-46	19h00	Uranus	focusliss		40-46	[6,0,-1.6]	0.3 (!?)	time traces varying by >>10kHz at 2mm !! set focus -1.6
47	19h20	Uranus	cross		46	[0,0,-1.6]	0.3 (!?)	time traces varying by >>10kHz at 2mm !! set pointing -5.1 4.6 (to go on 1mm ref det)
48	19h28	Uranus	cross		46	[-5.1,4.6,-1.6]	0.3 (!?)	PROBLEM !!!!
49	19h31	Uranus	cross		46	[-5.1,4.6,-1.6]	0.3 (!?)	OK, we're perfectly centred on 1mm ref det (residuals -0.1 0.5)
50	19h36	Uranus	focus track		48	[-5.1,4.6,-1.6]	0.3 (!?)
51	??	Uranus	??		48	[-5.1,4.6,-1.6]	0.3 (!?)
52-56	20h26	Uranus	focus track		53	[-5.1,4.6,-1.6]	0.3 still unstable, a bit better	focus OK at -1.6, at 2mm would be -1.1mm
57	20h34	Uranus	cross		55	[-5.1,4.6,-1.6]	0.2	more stable
58	20h37	Uranus	cross		55	[-0.2,-0.4,-1.6]	0.2	set pointing -3.7 5.5 to go on ref det 2mm
59	20h37	Uranus	cross		55	[-3.7,5.5,-1.6]	0.2	to check corrections
60	20h50	Uranus	OTFgeom		56	[-3.7,5.5,-1.6]	0.2	centred on 2mm ref det, FWHM at 1mm was 12" in last scans, 2mm focus a bit far, beam a bit in coma
61	20h50	na	skydip	160		[-3.7,5.5,-1.6]	0.2	former "skydipv2" (see Andrea)
