# # This file consists of a number of whitespace delimited columns. # The first two columns define a sector, and the rest of the columns # specify values for that sector. # # The first column specifies the starting angle of the sector (in degrees) # measured from the top (+Z axis) of the UN-ROTATED torus. Thus, the # spacecraft +Y axis is at 90 degrees and the -Y axis is at 270. # # The second column specifies the location of the send of the sector. # # The 3rd and 4th columns specifies the alignment error as follows. The # 3rd column specifies the alignment error offset, call it 'a'. The 4th # column specifies the uncertaintly in 'a'. Call it da. Then the actual # alignment error a ray will experience is given by 'a + da*g' where g is # a normally distributed random number with unit variance. # The units for the 3rd and 4th columns are in arc-minutes. # # The 5th and 6th columns specify the dp_over_p that the ray will experience. # Call the 5th column 'p' and the 6th column 'dp'. The dp_over_p value # will be computed via 'p + dp*g' where g is a normally distributed # random number with unit variance. # #-------------------------------------------------------------------------- # Notes on creating the values: # Start, Stop: 30 degrees per sector, then assume gratings fill sector # shell 1 has 9 facets, shell 3 has 7 # a : taken from Table 6.3 directly in arc minutes # da : (roll rms in arc seconds from most recent LR test) / 60. # p : (lr_active_period / LR_Average_Period of MEGs) - 1.0 # where average_LR_period_of_MEGs = 4001.17 # dp : taken from lr_active_plot, dp/p in the active region for the facet # #-------------------------------------------------------------------------- # Mis-aligned Gratings: Shell 1 # 1E4 ME1402: 30.*(10. + 5./9.) to 30.*(10. + 6./9.) # a= +5. # da= 50./60. # p=( 4001.66/ 4001.17)-1.= # dp= 174.0E-6 # # 1F4 MF1502: 30.*(9. + 5./9.) to 30.*(9. + 6./9.) # a= -6. # da= 28./60. # p=( 4000.88/ 4001.17)-1.= # dp= 57.0E-6 # # . . . . . . . . . . . . . . . . . .
