read_pha

Context: crates

Synopsis

Load a PHA file into a PHACrateDataset.

Syntax

read_pha(filename)

Description

  • filename - name of the file

The read_pha command loads the specified PHA file into a PHACrateDataset.

Example

>>> cds = read_pha("pha2")
>>> print(cds)

The output of the print command is:

   PHA Crate Dataset:
     File Name:         pha2
     PHA Type:          2
     Read-Write Mode:   rw
     Number of Crates:  3
       1)     Crate Type:        <IMAGECrate>
   Crate Name:        PRIMARY
   Crate Number:      1

       2)     Crate Type:        <TABLECrate>
   Crate Name:        SPECTRUM
   Crate Number:      2
   Ncols:             13
   Nrows:             12

       3)     Crate Type:        <TABLECrate>
   Crate Name:        REGION
   Crate Number:      3
   Ncols:             10
   Nrows:             36

In this example the PHA file is a type II grating dataset and was obtained from TGCat.
