load_arrays

Synopsis

Load data from variables containing arrays.

load_arrays( id, [array0, ..., arrayN, dstype] )

Description

The load_arrays command takes an arbitrary number of arrays and creates a dataset.

• id - the id of the dataset to use; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")
• 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> load_arrays("grid", xlo, xhi, counts, Data1DInt)

Use the arrays "xlo", "xhi", and "counts" to create a dataset with type Data1DInt and id "grid".
