#filename: hetgmp3D1996-11-01marxsectorN0002.tbl # #-------------------------------------------------------------------------- # 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 980930 values: # Start, Stop: 30 degrees per sector, then assume gratings fill sector # shell 1 has 9 facets, shell 3 has 7 # a : taken from $CALDBaxafcal/hetg/fcp/MEG_misaligned.rdb # 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 3 # 3EE2 ME1411: 30.*(4. + 5./7.) to 30.*(4. + 6./7.) # a= +7.6 # da= 32./60. # p=( 4000.18/ 4001.17)-1.= # dp= 44.0E-6 # # 3FF4 MD1312: 30.*(3. + 3./7.) to 30.*(3. + 4./7.) # a= -8.7 # da= 36./60. # p=( 4000.80/ 4001.17)-1.= # dp= 71.0E-6 # # 3FF5 MD1307: 30.*(3. + 2./7.) to 30.*(3. + 3./7.) # a= +24.8 # da= 19./60. # p=( 4000.45/ 4001.17)-1.= # dp= 54.0E-6 # # 3E1 ME1405: 30.*(10. + 6./7.) to 30.*(10. + 7./7.) # a= +7. # da= 34./60. # p=( 4000.15/ 4001.17)-1.= # dp= 41.0E-6 # # Rest of gratings: # Preliminary analysis of the XRCF Mg-K slit scan data # suggests a broad distribution in angle, approximated here # by setting a to +1 and -1 arc minute and assigning a da # of 1.5 arc minutes.
