bbody, zbbody: blackbody

A blackbody spectrum.

where

par1= kT | temperature keV |

norm= K | , where is the source luminosity in units of erg/s and is the distance to the source in units of 10 kpc. |

The zbbody variant allows an additional redshift parameter

where

z | redshift |

norm= K | , where is the source luminosity in units of erg/s and is the distance to the source in units of 10 kpc. |
