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.
