### WEATHER ###
Fine, seeing seems to be ok

### LOCATION ###
SUSI

### PROGRAM ###
Testing of siderostat pointings and image quality

### SIDEROSTATS ###
n1   s1   

### TARGETS ###
Bet-Cru to test 

Despite not changing the North focus today. The image quality of N1 is quite bad, with the ideal focus(265000) being at a position away from what was the ideal focus last night(245000). The flux through the mask also seems to be significantly lower (10000) and 13000 on tip/tilt. 

Fluxes:
N1: 10000 Tip/tilt 13000
S1:  20000 Tip/tilt 13000 

Focus: 
N1: 265000
S1 : 81000 (same as last night)

S1 pointing offsets :
210, 72
N1+S1 fringes at 1000um.

Note: Need to increase the speed of the spiral search

Switched to N3 to check if image quality in the north changes between sid 
N3 offsets (11, -167) quite different from last nights offsets...
S1 offsets (235, 97)
Fluxes:
N3:  9000 Tip/tilt 17000
S1: 16000 Tip/tilt 12000

N3+S1 fringes at 590um.

Trying S4 acqusition now (1:35am)
Star acquired at (-242, -25)
N1+S4 fringes at ~400um

Gain set to 200
Now onto Bet-Cen: offsets (-392, -29). Fringes at 360um. Double fringe packet seen.
Alf-Lup (hr 5469): Fringes at  um. (north 1 seem 2.5 times as bright as S4 on tip/tilt) No fringes found. One issue was that the crown wedge hit a limit.
