Wobbler Thorw

Double-beam pointing with heterodyne and bolometer to check the effective throw vs. the commanded one.

Observations

NOTE for pako/Hetrodyne

Use pakodev

pako> set priv staff
pako> swwobbler -XX XX
pako> pointing /double

To get the wobbler throw with MIRA

MIRA> let dopause yes

The wobbler throw fitted depends of the Wobbler phase and the velocity speed. The wobbler throw commanded is corrected of that dependence.

Tests: BR Wobbler Throws (arcsec): 30, 40, 50, 60, 70, 80, 90, 120 (Het.) BR Integ. Time (s)/Length (arcsec): 30/60, 30/90, 30/120, 30/150, 20/120, 20/140, 20/160 BR
