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)
$ PAKO> '''@ ./EMIR_SCRIPTS/skydip_EMIR.pako''' (it will first a calibration (HOT/COLD/SKY) 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' 'SkydipScanNumber' (to select the corresponding scan numbers)
$ MIRA> cal all (to calibrate all the data)
$ MIRA> solve 1, solve 2... (to obtain opacities)
