| Parameter | Mand | Type | Default | Constraints | 
| evlist | yes | dataset | evlist.ds | |
| 
    The input filtered event dataset.  It must contain the
    EVENTS table and exposure map extensions.  Not modified.
    All other file names required by this task are inferred by default
    from this one.
     | ||||
| srclist | no | dataset | ||
| 
    The input source definition dataset.  It must contain the
    SRCLIST table and the relevant selection region
    extensions.  Not modified.  The default file name is inferred from
    the input evlist name as: *SRCLI_????.* if there
    are ten characters before the suffix, and otherwise just     srclist.*.
     | ||||
| source | no | integer | non-negative | |
| 
    The INDEX number of an entry in the SRCLIST
    table.  This determines the incidence angle and selection regions.
    The default value, zero, indicates the SOURCEID attribute of
    the EVENTS table.
     | ||||
| order | no | integer | 1 | positive | 
| 
    The reflection order number.  This determines the energy selection
    region.
     | ||||
| withspectrum | no | boolean | yes | |
| 
    Enables output of the source spectrum (parameter
    spectrumset).  The type of this spectrum is controlled by
    parameter bkgcorrect.
     | ||||
| bkgcorrect | no | boolean | no | |
| 
    Enables background-correction of the source spectrum.
     | ||||
| spectrumset | no | dataset | ||
| 
    The output source spectrum dataset (OGIP-compliant format).
    The default file name is inferred from the input evlist name
    as: *SRSPEC
 | ||||
| withbkgset | no | boolean | yes | |
| 
    Enables output of the background spectrum (parameter bkgset).
     | ||||
| bkgset | no | dataset | ||
| 
    The output background spectrum dataset (OGIP-compliant format).
    The default file name is inferred from the input evlist name
    as: *BGSPEC
 | ||||
| rebin | no | integer | 1 | positive | 
| 
    The channel rebinning factor.  The events and exposure are
    rebinned going into the histogram, which gives a more stable
    result than if the full-resolution spectrum is rebinned later (a
    very minor point).
     | ||||
| edgechannels | no | integer | 2 | non-negative | 
| 
    The number of channels at the edges of each chip to be marked as
    bad in the output QUALITY column.  For reasons not well
    understood at this time, the two channels at either edge of every
    chip do not seem to be properly calibrated.
     | ||||
| exposed | no | real | 0.1 | 0-1 | 
| 
    Channels with less than this fraction of full exposure are marked
    as bad in the output QUALITY column.
     | ||||
| withfracexp | no | boolean | no | |
| 
    Enables addition of the non-standard (but harmless)
    FRAC_EXP column to the output spectra.  This is the
    fraction of full exposure in each channel.
     | ||||
| badquality | no | integer | 1 | 0-5 | 
| 
    The QUALITY column value used to indicate a bad channel.
    The default causes bad channels to be discarded automatically by
    XSPEC.  Advanced users of XSPEC may prefer to change this for
    diagnostic purposes.
