NAME

hlcircle - scan along an arc in the HL-plane in reciprocal space

SYNOPSIS

hlcircle  radius angle_start angle_end intervals time [expression]

DESCRIPTION

The hlcircle macro scans along a circular arc in the HL-plane in reciprocal space. The radius of the arc is given by radius and the arc runs from angle_start to angle_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 L are calculated for each point. You may, for example, supply an expression to calculate values for K or include expressions to offset the values of H and L.

EXAMPLES

hlcircle 1 0 90 10 60 "H += .5; L += .5"
 hlcircle 1 0 90 10 60 K=H/.125
 hlcircle 1 0 360 10 60 K=0
