LAMP function to correct polarization analysis data taken with the He3 filter ARW 06.09.04 NECESSARY VARIABLES: win=workspace with the data, must have the four polarization states as [[I00],[I01],[I10],[I11]] params=the fitted parameters to phi and trans This can be a 1 or 2D array, the second row in a 2D array is the error on the parameter params[0]=initial time for filter (t0) params[1]=initial polarization of 3He gas (P0He) params[2]=decay time of cell (t1) params[3]=polarizer inefficiency (p1) params[4]=gas pressure ([3He]) params[5]=wavelength (lambda) params[6]=first flipper efficiency (f1) params[7]=second flipper efficiency (f2) Cell thickness is fixed at 10 cm OPTIONAL VARIABLES: tol=the tolerance in the time for the measurement in seconds. The correction requires a time of measurement for the 4 flipper states This is taken as the average time of measurement. There will be some variation on the calculated average, normally +/- a second or two tol=2 should cover this and allow a proper correction to be made If the data falls outside this tolerance, an error message will be sent e.g. w5=d17_he3corr(w4,p,tol=2) CALLS TO: he3tptm, d17_errmsg Last modified: ARW 17.12.10
