Important: these notes are specific for observation in the Pool -- they are not the general Pako Cookbook!

IMPORTANT: The bolometer is refill once every ~2 days and then backup-heterodyne projects will be observed for about 5 hours or until the bolometer temperature is cooled down - This is independent of atmospheric conditions

Bolometer Observation

Currently we are using the 117 channels MAMBO2 bolometer built at the MPfR in Bonn (Germany) by the group of Ernst Kreysa. 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), setup the bolometer commands

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. BR

Skydip, pointing, focus

Pako>bt !Skydip at the current azimuth+start going down from high to low elevation

Do NOT use at present: (15.11.08, CK)

'''From Pako version 1.0.10 onwards we can also do skydips in continuus slew motion.'''

Pako> '''btslewu'''  !''Skydip at the current azimuth+start going up from low (~15º or 3.5 airmass) to high (~65º or 1.1 airmass) elevation'' [[BR]]
Pako> '''btslewd'''  !''Skydip at the current azimuth+start going down from high (~65º or 1.1 airmass) to low (~15º or 3.5 airmass) elevation''

Every 2 hours in stable atmospheric condition.

NOTE: For NCS testing use p90 or p120 for pointingBR 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)

Pako> bf Perform 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

Before an Onoff, be sure you are pointing with the right pixel (20).BR Do a pointing before each Onoff or map if they are longer than 30 mn.

[:CookbookPako#top:Top]

Calibration

Calibration on a [primary|secondary] calibrator

Pako> catalog source ihet BR Pako> source Calibrator_Name BR Pako> p60 BR Pako> set pointing azcor elcor BR Pako> onf4 ! Short Onoff integration (4 Subscans of 10 s) with central pixel 53

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 a case use a loop.

Pako> bsw throw !Setup the wobbler throw BR 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). BR Pako> bmapskew laz lel elstep azv skew !Setup an OTF map of laz azimuth length, lel elevation length, elstep elevation step, azv azimuth speed (arcsec/s) and a skew (step) in azimuth (arcsec). BR Pako> start !Start the map after you checked it is correct (it gives you the total integration time).

You should consider doing a pointing before AND after the map to check the tracking during the map.

Maps with the wobbler rotated [between -60 and 60 degrees]:BR

This feature needs special privilege for Pako. Ask the AoD. BR

Pako> set 2nd wobblerRotation !Setup the wobbler rotation with the angle wobblerRotation [degree] BR Pako> ... Do a pointing before with the wobbler rotated BR Pako> bmap-rotate laz lel elstep azv wobblerRotation ! Setup an OTF map of laz azimuth length, lel elevation length, elstep elevation step, azv azimuth speed (arcsec/s) and the wobblerRotation angle [degree] BR Pako> start BR Pako> ... Do a pointing after the map Pako> set 2nd 0. !Setup the wobbler rotation back to zero.

The speed should not be larger than ~8 arcsec/sec

NOTE: BR roff20 : set the pixel 20 for on-off (most sensitive one). BR roff53 : set the central pixel 53 (default with @wbolo) BR BR
