Description: New MSE calibration                                     

 The MSE offset calibration has been updated on July 6, 1993.
 The new calibration is based on a large set of data obtained in July.
 Unfortunately, the data are not entirely consistent due, most
 probably, to extraneous polarization produced by scattered light.
 Thus, the present calibration is a result of very careful analysis
 taking into account the previous calibrations, etc. As usual, this is
 NOT the final calibration but the best we can have at this time.
 It is estimated that the absolute error of the tilt angle determination
 (the calibration error) is still of the order of 0.5 degree.
 The MSE data in EFIT should be used with weight of 0.5
 (fwtgam = 8*0.5).
 
 The EFIT q-profiles obtained with the new calibration seem to indicate
 somewhat higher values of q0 than obtained with the previously used
 calibration. Thus, if the current profile is an important quantity in
 your analysis the fits should be re-run. (As of 6-JUL-93, EFIT will
 use the new calibration).
