DMC_grat_scan_nochop

The only role of PACS' DMC scripts is the computation of its duration, needed as input variable when starting the associated OBCP.

// Purpose      : Compute duration of DMC Sequence 13 : grating scan without
//                chopping
// Description  : For all internal details about DMC Seq 13, see PACS-ME-LI-005
//                and pseudo code here. Identical to "Grating line scan with
//                two or three position choping" but with out choping on source.
//                Meant mostly for ILT to allow for fast execution of
//                measurements on "absolute" flux sources.
// Comments     : 1. No single command is executed here, only the duration is
//                   computed here. Hence, not all parameters of the actual DMC
//                   Seq. are relevant here!
// Version      : 2.0
// History      : 1.0 05-Apr-2005 Creation by PR
//                2.0 06-Apr-2005 Completed by DAC with pseudo code and
//                                full duration computation.
//                2.1 25-apr-2005 DAC Arranged arguments in P#1,#2 order
//                                Renamed DMC_grat_scan_nochop as OBCP
//
