load_crab_flux_points

gammapy.datasets.load_crab_flux_points(component='both')[source]

Load published Crab pulsar and nebula flux points.

Besides the usual flux point columns, this table contains the following two columns:

  • component : {‘pulsar’, ‘nebula’}
  • paper : Short string describing which point originates from which paper.

TODO:

  • Add link to Crab flux point tutorial in Gammapy where these points are plotted.
  • Add html links to ADS directly in the docstring and as a table column.
Parameters:

component : {‘pulsar’, ‘nebula’, ‘both’}

Which emission component to include
Returns:

flux_points : Table

Flux point table

Notes

This data compilation is from Buehler and Blandford, Rep. Prog. Phys. 77, 2014. It was contributed to Gammapy directly by Rolf Buehler via a pull request.

The data for the nebula were taken from Meyer et al. Astron. Astrophys. 523 2010 with the addition of the Fermi-LAT measurement reported in Buehler et al. ApJ 749 2012.

The pulsar spectrum is reproduced from Kuiper et al Astron. Astrophys. 378 2001 . Additionally shown are infrared measurements reported in Sollerman et al. ApJ 537 2000 and Tziamtzis et al. Astron. Astrophys. 508 2009, radio measurements referenced in Thompson et al. ApJ 516 1999 and gamma-ray measurements referenced in Aleksic et al. ApJ 742 2011, Aliu et al. Science 334 2011, Aleksic et al. Astron. Astrophys. 540 2012 and Abdo et al. Astrophys. J. Suppl. Ser. 208 2013.
