Arrays status tonight: (126 pixels 2mm, 90 pixels 1.25mm):

Plan for tonight (126 pixels 2mm, 90 pixels 1.25mm)

Pointing model was updated by Juan Penalver:

use 31 pointing values obtained yesterday
dispersion goes from 2.8 to 2.5 arcsec.
DeltaP1=-3.46+-0.72
DeltaP7=+1.88+-0.44

Nasmyth offsets : 0, 0

Set pointing : 0, 0

Set Focus : -1.6 mm

-Plan for tonight (126 pixels 2mm, 90 pixels 1.25mm): Plan for tonight (126 pixels 2mm, 90 pixels 1.25mm): 126 pixels 2mm - good noise; 8 pixels 1mm noise should be good (reduce the number of pixels so that total tones power below amplifier saturation).
