SYNOPSIS

hkradial angle start end intervals time [expression]

DESCRIPTION

The hkradial macro scans along a radius in the HK-plane in reciprocal space. The angle of the arc from the positive H axis is given by angle and the scan runs from the radius given by start to the radius given by end. The number of data points collected will be intervals+1. Count time is given by time, which if positive, specifies seconds and if negative, specifies monitor counts.

The optional last argument can supply expressions to be evaluated after H and K are calculated for each point. You may, for example, supply an expression to calculate values for L or include expressions to offset the values of H and K.
