Skydips with EMIR

Go to the Run9 main page.

Starting PaKo

To run the observations in PaKo do:

$ PAKO> @ ./EMIR_SCRIPTS/setup.pako (to setup the line catalog, line sources, etc.)
$ PAKO> @ ./EMIR_SCRIPTS/receiver_E1_NIKA2.pako (for the 2.0 mm observations or receiver_E2_NIKA2.pako for the 1.15 mm observations)
$ PAKO> @ ./EMIR_SCRIPTS/backend_NIKA2.pako (to setup backends BBC and NBC to record the USB and LSB)
$ PAKO> source YOUR-SOURCE /cat * (set a strong continuum source to correct pointing and focus)
$ PAKO> @ ./EMIR_SCRIPTS/pointing.pako (to calculate pointing offsets. Script includes a calibration)
$ PAKO> set pointing az el (introduce the pointing corrections az and el obtained from the fit to the measured flux of the source)
$ PAKO> @ ./EMIR_SCRIPTS/focus.pako (to calculate the focus correction)
$ PAKO> set focus fz (introduce the focus correction fz obtained from the fit to the measured flux of the source)
*** BEFORE RUNNING THE SKYDIP: EDIT THE SCRIPT AND SET THE AZIMUTH USED FOR THE NIKA2 DKYDIPS***.
$ PAKO> @ ./EMIR_SCRIPTS/skydip_EMIR.pako (it will first do a calibration (HOT/COLD/SKY) at 65° and then perform 8 measurements at airmases from 1.10 to 3.20 by 0.30, equivalent to elevation range from 65.4° to 18.2°. The scritp can be adapted to other settings if needed).

The data reduction has to be don in MIRA. For this, ssh -X to mrt-lx3 and run:

$ t22@mrt-lx3:~$ mira (to start MIRA)
$ MIRA> file in “~/observationData/imbfits“ (to load the recorded imbfits containig the skydips mesurements)
$ MIRA> find /OBSERVED yyyy-mm-dd (to load the scans only for a given day) 
$ MIRA> scan 'calScanNumber' (to select the calibration scan)
$ MIRA> cal all (to calibrate all the data)
$ MIRA> scan 'SkydipScanNumber' (to select the skydip scan)
$ MIRA> cal all (to calibrate all the data)
$ MIRA> solve 1, solve 2... (to obtain opacities)
