Bolometer's Observation:

The most important commands of the old system have been adapted to the NCS. Here is a typical starting sequence for the bolometer.

Setup the Bolometer

Pako> @wbolo ! Mambo2, central pixel 53, short onoff (@onf4)

Sources Catalog

Pako> catalog source pool ! Setup the project source catalog BR Pako> catalog source ihet ! Setup the pointing/calibration source catalog

Pointing sources: J1419+240 not 1419+240

Focus, pointing, Skydip

Pako> focus 1.1 BR Pako> start ! Start the focus BR Pako> set focus _sfcz_ !Correct the focus with _sfcz_. Correction from MOPSIC (@f or @fsn for weak sources)

Do a focus when atmospheric conditions are changing, typically after sunset/sunrise

Pako> p40 !Short length pointing for weak sources+start BR Pako> p60 !Long length pointing for strong sources+start BR Pako> set pointing _azcor_ _elcor_ !Correct the pointing with _azcor_ and _elcor_. Correction from MOPSIC (@p or @psn for weak source)

Before each Onoff or map if they are larger than 30 mn.

Pako> bt !Skydip at the current azimuth+start

Every 2 hours in stable atmospheric condition.

Before an Onoff, be sure you are pointing with the right pixel (20).

Calibration

Calibration on a [primary|secondary] calibrator

Pako> @wbolo BR Pako> catalog ihet Calibrator_Name BR Pako> p60 BR Pako> SET POINTING _azcor_ _elcor_ BR Pako> @onf4 ! Shor Onoff integration (4 Subscans of 10 s)
