…rom pfb-style models.
* Fix version drift. * Bump to 0.2.0 * Inspect envvar for scheduler address when one isn't specified. * Encode environment varraible as ascii. * Simplify.
…o a dask-ms fragment.
* Fix version drift. * Bump to 0.2.0 * Initial commit of basic plotting functionality. * Change naming convention. * Improve transform argument. * Simplify transform selection. * Add rudimentary time and frequency selection. * Checkpoint ploter changes. Can now handle scans and spws, but is very slow. * More work on plotter - can now plot datasets in parallel. * Some tidying. * Slightly improve plot speed. Dominant cost is still saving the figures. * Commit some minor changes which speed up figure saving. * Lots of tiny fixes. * Tiny cosmetic changes. * Add custom tick formatter so that plots are the same size regardless. * Add matplotlib dependency. * Rework construction of plotting dictionary. Add a few utility functions which will likely be useful in other places in QC. * Rename variable to avoid confusion. * Fix bug affecting recursive grouping. * Avoid copies in grouping code. * Checkpoint work on extending functionality. * Make plotter more powerful. Add colourization option. Begin simplifying interface. * Allow user specification of colourmap. * Add plotsize parameter.
* Fix version drift. * Bump to 0.2.0 * Fix #293.
* Fix version drift. * Bump to 0.2.0 * Add optional label and single field selection to backup app * remove item instead of pop@index * do not .remove() from xds_list * Simplify using some existing functionality. --------- Co-authored-by: JSKenyon <jonathan.simon.kenyon@gmail.com> Co-authored-by: landmanbester <lbester@ska.ac.za>
* Fix version drift. * Bump to 0.2.0 * Setting MAD threshold to zero will disable flagging on a given statistic.
* Fix version drift. * Bump to 0.2.0 * Disable flagging based on off-diagonal correlations in the mad flagger by default. This should make the mad flagger less agressive on data with unmodelled polarised emission.

This PR is a WIP which integrates basic degridding functionality into QuartiCal via ducc0 and the prototype universal model format produced by pfb-clean
model2comps.Initial experiments are promising (model visibilities are produced and calibration runs through). There are still a large number of sharp edges and missing features but this PR will allow us to keep track of developments.
