The purpose of this procedure is to monitor the mechanical flexures produced into EMMI - REMD with the rotator at different angles measuring the shifts of image on CCD in x,y and focus.
The procedure takes n exposures of a 1"x3.2" slit seen through
Focus Wedge , changing the rotaror angle by a rotator step editable in the Remd_tec_Flexure.obd,
then, measures the displacement of the image on the CCD in x
and y directions for the leftmost image
and dy ( defocussing) for the
( x axis is along the dispersion and y axis is across the dispersion ).
The RemdTiFlexure.seq template moves rotator b from wemmi.
