EMMI - REMD Focus Flexure Monitoring


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 rightmost image
( x axis is along the dispersion and y axis is across the dispersion ).

The RemdTiFlexure.seq template moves rotator b from wemmi.
