/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 54421.358177 0.000347 0.15494 0.01177 0.98333 0 24.50103 0.67986 21.91429 0.60808 3.79628 0.26844 3.39548 0.24010 54421.358834 0.000310 0.16917 0.01312 0.99065 0 24.75248 0.73236 22.13919 0.65504 4.18733 0.30008 3.74524 0.26840 54421.359511 0.000367 0.14212 0.01082 0.98425 0 25.10025 0.67786 22.45024 0.60630 3.56727 0.25394 3.19065 0.22713 54421.360252 0.000373 0.14856 0.01144 0.98450 0 23.53554 0.64675 21.05073 0.57847 3.49641 0.25160 3.12727 0.22504 54421.360941 0.000315 0.17883 0.01398 0.99083 0 22.99103 0.70082 20.56371 0.62683 4.11152 0.29586 3.67744 0.26462 54421.361574 0.000318 0.17711 0.01391 1.00000 0 22.68757 0.68981 20.29228 0.61698 4.01812 0.29108 3.59389 0.26035 54421.362549 0.000657 0.16107 0.00929 0.98405 0 22.58151 0.48045 20.19742 0.42973 3.63730 0.19509 3.25329 0.17449 54421.427551 0.000391 0.15439 0.01197 0.99259 0 24.76622 0.70203 19.09806 0.54136 3.82372 0.27593 2.94860 0.21278 54421.428356 0.000414 0.14544 0.01145 1.00000 0 24.28987 0.67637 18.73073 0.52157 3.53271 0.26019 2.72419 0.20064 54421.429154 0.000385 0.15654 0.01221 1.00000 0 24.61905 0.70834 18.98457 0.54623 3.85396 0.27927 2.97191 0.21536 54421.429912 0.000373 0.16033 0.01251 1.00000 0 24.78285 0.71641 19.11088 0.55245 3.97346 0.28793 3.06407 0.22203 54421.431128 0.000842 0.15190 0.00833 0.98342 0 23.57817 0.46536 18.18191 0.35885 3.58157 0.18314 2.76187 0.14122 54421.496831 0.000388 0.15215 0.01178 0.99254 0 21.95904 0.61689 19.52697 0.54857 3.34106 0.24106 2.97102 0.21436 54421.497577 0.000359 0.16043 0.01240 1.00000 0 22.44092 0.64799 19.95548 0.57622 3.60024 0.25802 3.20150 0.22944 54421.498318 0.000382 0.15550 0.01197 0.97727 0 22.25570 0.62453 19.79077 0.55536 3.46070 0.24802 3.07741 0.22055 54421.499053 0.000353 0.16163 0.01281 1.00000 0 22.34335 0.65111 19.86872 0.57900 3.61139 0.26626 3.21141 0.23677 54421.499759 0.000353 0.16914 0.01311 0.98361 0 21.99566 0.64801 19.55954 0.57624 3.72025 0.26662 3.30822 0.23709 54421.500740 0.000628 0.14572 0.00882 0.99078 0 22.88428 0.49362 20.34974 0.43895 3.33467 0.18847 2.96534 0.16760
