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