ERI1_FOLDN_AST

Fold channel spectra through ASTERIX type energy response

Invocation

CALL ERI1_FOLDN_AST( NENER, NSPEC, ESPEC, NRMF, CIND,

Description

Folds NSPEC energy spectra through the ASTERIX style energy response specified by CIND,EIND and RESP. These 3 arrays store the indices and values of the sparse 2D response array. The output is NSPEC channel spectra.

Arguments

• NENER = INTEGER (given)
  Number of energy space bins
• NSPEC = INTEGER (given)
  Number of spectra
• ESPEC[NENER,NSPEC] = REAL (given)
  Energy space spectra
• NRMF = INTEGER (given)
  Number of non-zero response elements
• CIND = INTEGER (given)
  Channel indices of non-zero response elements
• EIND = INTEGER (given)
  Energy indices of non-zero response elements
• RESP = REAL (given)
  Response values
• CSPEC[NCHAN,NSPEC] = REAL (returned)
  Channel space spectra
• STATUS = INTEGER (given)
  The global status.
