NDMapper change log

0.3 (unreleased)

  • No changes yet. Planning to split out NDProcess module.

0.2 (2016-10-06)

  • Add wrapper steps for gmos.spec.ifu data cube mosaicking and logarithmic re-binning, using my PyFU Python package.
  • Add cosmetics.clean_cosmic_rays step, based on McCully's lacosmicx (fast Cython implementation of LA Cosmic algorithm; currently requires forked version at https://github.com/jehturner). Also supporting code for fitting.
  • Add gemini.clean_pixels wrapper for gemfix (& work around IRAF corrupting 'MDF' extensions in the latter).
  • Add gmos.spec.normalize_QE wrapper for gqecorr (to correct differences in QE variation with wavelength between CCD chips).
  • Add gmos.spec.ifu.subtract_bg wrapper for gfscatsub (scattered light subtraction) and associated gmos.spec.ifu.background_regions wrapper for gffindblocks (to identify gaps between blocks of fibres). Generalize the calibration association slightly to support the latter.
  • Pass through additional options in gmos.spec.ifu.extract_spectra, to help control the results.
  • Allow associating MDFs as calibrations (so they can differ between inputs when the numbers of detectable fibres differ).
  • Automatically map 'LTT' standard names to IRAF's onedstds 'l' convention, when finding the appropriate look-up table based on meta in gmos.spec.
  • Add a shift_spectra step for gmos that can apply a zero-point correction to the IRAF wavelength database(s) associated with a DataFileList (with the shift values also optionally associated as calibrations).
  • New reload & save convenience methods in DataFileList.
  • Add initial arithmetic operators to NDLater and DataFile (with support for specifying an output filename when called as methods). In the process, add some missing NDDataArray attributes.
  • Support assignment to a DataFile index (__setitem__).
  • NDLater compatibility with AstroPy 1.2.1.
  • Support assignment to TabMapIO.table (for updating MDFs; still missing a proper public API).
  • Change filename prefix for cosmetics.add_bpm from 'b' to 'k', to avoid (unexpected) confusion with scattered light subtraction.

0.1.2 (2016-03-26)

  • Fix libutils.splitext to ignore the path when splitting on the first dot, in case directory names contain dots (specifically temp directories created by py.test).
  • Include FITS data in MANIFEST.in & setup.py so the tests can be run from an installed copy of the package (in particular one created by py.test).
  • Configure py.test not to capture stdout (which causes importing pyraf to fail due to incompatible redirection) and to skip a doctest with no data, avoiding failures when using py.test instead of nose.
  • Determine the path to FITS data in the tests without using astropy get_pkg_data_filename, to avoid remote data errors from py.test.
  • Enabled testing with Travis.
  • Initial Python 3 compatibility changes, mainly for the data submodule.

0.1.1 (2016-03-12)

  • Clarify that processing library outputs parameters are now intended only to specify filenames (rather than supporting shared data, at least for now) and rename them accordingly, to out_names.
  • Fixed a run_task failure when a DataFile modified in memory was passed as the input to multiple IRAF steps, which raised an IOError second time, due to sharing identically the same NDLater instances (& TabMapIO list) when instatiating one DataFile from another, such that run_task ended up modifying the NDMapIO instances of its inputs with a temporary filename.
  • Include missing add_bpm in cosmetics name space.

0.1 (2016-03-01)

  • PyPI test release.
