ERI_FOLD

Fold an energy spectrum through the instrument responses

Invocation

CALL ERI_FOLD( NENER, ESPEC, NCHAN, RMFID, ARFID, CSPEC, STATUS )

Description

Folds the supplied energy spectrum through the energy response supplied. The response is in the form of a redistribution matrix and an area response. If the former is normalised then the second object is required to convert to counts/cm**2.

For details of how different forms of response are handled see the ERI_FOLDN routine.

Arguments

• NENER = INTEGER (given)
  Number of energy space bins for output spectrum
• ESPEC[] = REAL (given)
  Input energy space spectrum
• NCHAN = INTEGER (given)
  Number of channels in output spectrum. Used to check against response
• RMFID = INTEGER (given)
  ADI identifier of RedistributionMatrix object
• ARFID = INTEGER (given)
  ADI identifier of AreaResponse object
• CSPEC[] = REAL (returned)
  The channel space spectrum
• STATUS = INTEGER (given and returned)
  The global status.
