3.9.3. - Basic Reciprocal Space Scans
hscan start_H finish_H intervals time kscan start_K finish_K intervals time lscan start_L finish_L intervals time hklscan s_H f_H s_K f_K s_L f_L intervals time hklmesh Q1 s_Q1 f_Q1 intervals1 Q2 s_Q2 f_Q2 intervals2 time
The first three scans are special cases of
hklscan
, as in
def hscan ' if ($# != 4) { print "Usage: hscan start finish intervals time" exit } waitall; getangles; calcHKL hklscan $1 $2 K K L L $3 $4 '
hklmesh
does a grid
scan of two reciprocal coordinates, where
Q1
and
Q2
are literally
H
, K
or
L
, and
Q1
!=
Q2
.
A
waitmove
, getangles
and
calcHKL
are done at the start of the scan to obtain
the current diffractometer position
to determine the values of the unspecified coordinates
in
hscan
, kscan
, lscan
and
hklmesh
.
