Release Notes

5.0.0 (2024-07-03)

  • potentially breaking change: xspec: in BXA v5, priors now use min/max soft parameter limits instead of hard parameter limits. That is, among “min, bottom, top, and max”, BXA<5 used min and max, while BXA>=5 uses bottom and top.

  • xspec: compute fluxes for multi-source and multi-spectrum cases (thanks @DaKalt)

  • sherpa: smooth interpolation in CDF prior file interpolation

  • add eROSITA background file

4.1.4 (2024-05-26)

  • fix in BXA/sherpa PCA background fitting. Previously, emission lines were never added.

    • This means that versions before 4.1.3 and after will give different background fits

    • The old behaviour can be recovered with auto_background(max_lines=0).

  • add Bayesian workflow tutorial

4.0.0 (2021-01-06)

  • Make ultranest default, remove multinest.

3.4 (2019-05-26)

3.3 (2020-01-28)

3.2 (2020-01-12)

  • circumvent xspec numerical interpolation issues (Lepsilon parameter)

3.1 (2019-10-21)

  • Make multinest optional, allow ultranest

2.6 (2019-05-21)

  • replace outdated progressbar with tqdm
