User Parameters - Bandpass Calibration ====================================== These parameters govern all processing used for the calibrator observation. The requested measurement set is split up by beam and scan, assuming that a given beam points at 1934-638 in the correspondingly-numbered scan. While it is possible to use the ``BEAM_MIN`` and ``BEAM_MAX`` parameters to specify a given range of beams to process for the science field, only the ``BEAM_MAX`` parameter is applied to the bandpass calibrator processing. All beams up to ``BEAM_MAX`` are split & flagged, and have their bandpass solved for. This is due to the particular requirements of :doc:`../calim/cbpcalibrator`. If the bandpass calibration observation is long, and you just wish to use a portion of it for bandpass calibration, then you can specify a time range through ``SPLIT_TIME_START_1934`` and ``SPLIT_TIME_END_1934``. If either is not given, the start or end time are taken to be the start or end of the observation respectively. The default behaviour is to flag the data with :doc:`../calim/cflag`. In this case, the MS is flagged in two passes. First, a combination of selection rules (allowing flagging of channels, time ranges, antennas & baselines, and autocorrelations) and (optionally) a simple flat amplitude threshold are applied. Then a sequence of Stokes-V flagging and dynamic flagging of amplitudes is done, integrating over individual spectra. Each of these steps is selectable via input parameters. There is an option to use the AOFlagger tool (written by Andre Offringa) to do the flagging. This can be turned on by ``FLAG_WITH_AOFLAGGER``, or ``FLAG_1934_WITH_AOFLAGGER`` (to just do it for the bandpass calibrator). You can provide a strategy file via ``AOFLAGGER_STRATEGY`` or ``AOFLAGGER_STRATEGY_1934``, with access to some of the aoflagger parameters provided - see the table below. Then the bandpass table is calculated with :doc:`../calim/cbpcalibrator`, which requires MSs for all beams to be given. This is a parallel job, the size of which is configurable through ``NUM_CPUS_CBPCAL``. If a second processing job is run with a higher ``BEAM_MAX`` (and hence wanting to use beams not included in a previous bandpass solution), the bandpass table is deleted and re-made once the new beams are split and flagged. The cbpcalibrator job can make use of one of two scripts developed in the commissioning team. The first, ``plot_caltable.py`` from ACES both plots the bandpass solutions (as a function of antenna, beam and polarisation), and smooths the bandpass table so that outlying points are interpolated over. This produces a second table (with ".smooth" appended to the name), which will then be applied to the science data instead of the original. There are a number of parameters that may be used to tweak the smoothing - this is intended to be an interim solution until this functionality is implemented in ASKAPsoft. The second script, ``smooth_bandpass.py``, does the smoothing of the bandpass via harmonic fitting, in a way that is robust to portions of the spectra being flagged. If either of these options are used, a bandpass validation script is run, producing plots that can describe the quality of the bandpass solutions. Finally, the bandpass solutions can be applied back to the 1934 datasets themselves. This will permit possible diagnostic analysis of the quality of the bandpass solution. Additionally, we now have the option to derive instrumental on-axis polarisation leakages from the 1934-638 data. The bandpass calibrated 1934-638 measurement sets are further flagged, spectrally-averaged to 1MHz resolution, flagged again, and then leakages derived. To turn this on, use ``DO_LEAKAGE_CAL_CONT=true``. The derived solutions can then be applied to continuum averaged, and self-calibrated science data using ``DO_APPLY_LEAKAGE=true``. The derivation and application of leakage calibration is done indepdendently on each continuum channel. +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | Variable | Default | Parset equivalent | Description | +===============================================+===========================================+========================================================+===========================================================+ | ``DO_SPLIT_1934`` | true | none | Whether to split a given beam/scan from the input 1934 MS | +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | ``JOB_TIME_SPLIT_1934`` | ``JOB_TIME_DEFAULT`` (24:00:00) | none | Time request for splitting the calibrator MS | +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | ``DO_FLAG_1934`` | true | none | Whether to flag the splitted-out 1934 MS | +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | ``JOB_TIME_FLAG_1934`` | ``JOB_TIME_DEFAULT`` (24:00:00) | none | Time request for flagging the calibrator MS | +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | ``DO_FIND_BANDPASS`` | true | none | Whether to fit for the bandpass using all 1934-638 MSs | +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | ``JOB_TIME_FIND_BANDPASS`` | ``JOB_TIME_DEFAULT`` (24:00:00) | none | Time request for finding the bandpass solution | +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | **Preparing the calibrator datasets** | | | | | | | | | +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | ``MS_BASE_1934`` | 1934_SB%s_%b.ms | none | Base name for the 1934 measurement sets after splitting. | | | | | The wildcard %b will be replaced with the string "beamBB",| | | | | where BB is the (zero-based) beam number, and | | | | | the %s will be replaced by the calibration scheduling | | | | | block ID. | +-----------------------------------------------+-------------------------------------------+--------------------------------------------------------+-----------------------------------------------------------+ | ``CHAN_RANGE_1934`` | ``""`` | channel (:doc:`../calim/mssplit`) | Channel range for splitting (1-based!).
