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) BR (!) Do a focus when atmospheric conditions are changing, typically after sunset/sunrise

Pako> p40 !Short pointing for weak sources+start BR Pako> p60 !Long 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 longer 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)

<!> You may do a short @onf4 after a normal pointing to monitor the pointing source flux.

Onoff and map

Pako>@onf 20 30 !Perform an on-off integration of 20 subscans of 60s with a wobbler throw of 30" BR Pako> @onf30 !Some project may have their own on-off macro

<!> Don't try to make very long integration, you may loose the complete scan. In such case use a loop.

Pako>bmap laz lel elstep azv' !Setup an OTF map of laz azimuth length, lel elevation length, elstep elevation step and azv azimuth speed (arcsec/s)
