AHELP for CIAO 4.6 Sherpa v2

unpack_arrays

Context: data

Synopsis

Unpack arrays from a CrateData object

Syntax

unpack_arrays( array0, ..., arrayN, [dstype] )

Description

The unpack_arrays command unpacks one or more arrays from a CrateData object into a Sherpa data object.

  • array0 ... arrayN - the input arrays
  • dstype - dataset type: Data1D, Data1DInt, Data2D, Data2DInt, DataPHA, DataIMG; default=Data1D

The data must be listed in the order required by the dataset type:

  • Data1D: x, y, staterror=None, syserror=None
  • Data1DInt: xlo, xhi, y, staterror=None, syserror=None
  • Data2D: x0, x1, y, shape=None, staterror=None, syserror=None
  • Data2DInt: x0lo, x1lo, x0hi, x1hi, y, shape=None, staterror=None, syserror=None
  • DataPHA: channel, counts, staterror=None, syserror=None, bin_lo=None, bin_hi=None, grouping=None, quality=None, exposure=None, backscal=None, areascal=None
  • DataIMG: x0, x1, y, shape=None, staterror=None, syserror=None, sky=None, eqpos=None, coord=logical

Example

sherpa> grid=unpack_arrays(xlo, xhi, counts)

Unpack the arrays "xlo", "xhi", and "counts" to create a data object named "grid".
