2.0.0

  • Major refactoring of simulation modules

1.2.0

  • Addition of the obs_config module to estimate data volumes of NenuFAR observations. This can be done for all the receivers and configuration modes. Observation configurations can either be set individualy for each receiver or given as parset files or list of parset files [#43].

  • Module schedule to automatically schedule observation bookings via deterministic or genetic algorithm.

  • Method lnaGain() to get the NenuFAR Low Noise Amplifier gains interpolated at given frequencies.

1.1.0 (2020-11-18)

  • Extrapolation of NenuFAR antenna model (nenufar_ant_gain()) above 80 MHz [#22].

  • Implementation of ObsDatabase class, which enables queries over the NenuFAR BST database in order to seach for particular past observations within a given time_range and/or freq_range and/or around a given sky position fov_center with a given search radius fov_radius.

  • Addition of a text and a contour option to plot() aiming at overplotting text (such as source names) at some given equatorial positions or contours from a corresponding HEALPix image.

  • UVW computation corrected (sign convention in order to call imaging TF as \(\int V e^{-2\pi i (ul + vm)}\, du\, dv\)) [#23].

  • NenuFAR data rate estimation implemented (data_rate()).

  • Conversion between frequencies and subband indices freq2sb() and sb2freq().

  • Dispersion delay added (dispersion_delay()).

  • Implementation of Dynspec to read/de-disperse/rebin (in time and/or frequency) high-rate UnDySPuTeD time-frequency data (or DynSpec data) [#30].

  • Correct for 6 min jumps in Undysputed DynSpec data [#32].

  • Implemented background computation for SData objects (background and fbackground) as well as a plotting method plot().

  • SQL database (sqldatabase).

  • Add functions to get a source coordinates and compute the horizontal coordinates versus time (getSource() and altazProfile()).

  • Plot of observation pointing files alatazA and altazB (plotPointing()).

  • Correction of bugs and improvement of the astro module [#38].

  • Faster version of equatorial/horizontal coordinates conversion (toAltaz()).

  • Addition of Earth coordinates converters (astro: l93_to_etrs(), geo_to_etrs(), etrs_to_geo(), etrs_to_enu(), enu_to_etrs()).

  • Near-field computation added for Cross-Correlation Statistics data (nearfield()).

  • Easy acces to LOFAR Skymodel (LofarSkymodel).

  • SST reading (SST_Data)

1.0.0 (2020-04-29)

Major refactoring of the original nenupy package.
