Description

A number of bug fixes and added functionality, highlights below (for full list see the changelog):

UVData:

  • New upsample_in_time, downsample_in_time, and resample_in_time methods.
  • Support for rephasing phased data including on read, __add__ and fast_concat so that files with different phasing can be read in together.
  • New sum_vis and diff_vis methods for summing or differencing visibilities in the data_array.
  • New read_mwa_corr_fits method for reading in MWA correlator gpubox files and applying cable corrections.
  • Significantly improved support for metadata only objects (objects with everything except the data_array, flag_array, nsample_array defined).
  • New copy method, which can optionally make a copy of just metadata.

UVBeam:

  • Support for reading the MWA full embedded element beam into a UVBeam object.

UVCal:

  • FIXED: A bug in UVCal.read_fhd_cal that caused calibration solutions to be approximately doubled.
  • New utils.uvcalibrate function to apply calibration of UVData from a UVCal object.

UVFlag:

  • Significant improvements, including integration with the standard UVBase object.

Packaging:

  • h5py is now a required package instead of an optional one.
  • Optional HEALPix functionality is now provided via astropy_healpix rather than healpy.
