PHA routines 

  •  int ReadPHAtypeI(char *filename, long PHAnumber, struct PHA *phastruct)

    Read the type I SPECTRUM extension from a FITS file - if there are multiple SPECTRUM extensions then read the one with EXTVER=PHAnumber. 

  •  int ReadPHAtypeII(char *filename, long PHAnumber, long NumberSpectra,
                   long *SpectrumNumber, struct PHA **phastructs)

    Read the type II SPECTRUM extension from a FITS file - if there are multiple SPECTRUM extensions then read the one with EXTVER=PHAnumber. Within the SPECTRUM extension reads the spectra listed in the SpectrumNumber vector. 

  •  int WritePHAtypeI(char *filename, struct PHA *phastruct)

    Write the spectrum to a type I SPECTRUM extension in a FITS file. 

  •  int WritePHAtypeII(char *filename, long NumberSpectra, 
                    struct PHA **phastructs)

    Write the multiple spectra to a type II SPECTRUM extension in a FITS file. 

  •  int ReturnPHAtype(char *filename, long PHAnumber)

    Return the type of the SPECTRUM extension with EXTVER=PHAnumber. 

  •  void DisplayPHAtypeI(struct PHA *phastruct)

    Write information about the spectrum to stdout. 

  •  void DisplayPHAtypeII(long NumberSpectra, struct PHA **phastructs)

    Write information about multiple spectra to stdout. 

  •  int RebinPHA(struct PHA *phastruct, struct BinFactors *bin)

    Rebin spectrum. 

  •  int CheckPHAcounts(char *filename, long PHAnumber)

    Return 0 if COUNTS column exists and is integer or COUNTS column does not exist. 

  •  long ReturnNumberofSpectra(char *filename, long PHAnumber)

    Return the number of spectra in the type II SPECTRUM extension which has EXTVER equal to PHAnumber.
