Wherever possible, the point at which these other data
(which we will call reflection data ) are read is accessible to
the user, so that if he has data
in some strange format he can still read them. An example of this is
in the various Least Squares Refinement main programs like
SFLSQ,
MAGLSQ,
which actually contain the READ and FORMAT statements for the reflection
data. Several alternative formats are already provided; there is also a
data input type 0, indicating that the data will be provided, a line at a
time, by successive calls to SUBROUTINE QLSQIN, which the user must provide.
In general, any SUBROUTINE QxxxIN is a user-provided input routine for
reflection data. (The user need not concern himself with special formats
or a routine QLSQIN if he has data in some standard format known to the
system; there is a dummy routine
QLSQIN in the Library, which will be
superseded by any routine of the same name if the user provides one.)
