/* ** ** 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 57908.159236 0.000379 0.19985 0.01568 0.99237 0 16.76267 0.53355 15.29586 0.48685 3.35010 0.24033 3.04932 0.21875 57908.159974 0.000359 0.21748 0.01743 0.99194 0 15.93530 0.53452 14.67352 0.49214 3.46553 0.25221 3.18825 0.23206 57908.160689 0.000356 0.22372 0.01783 0.98374 0 15.84108 0.53769 14.58103 0.49495 3.54405 0.25547 3.26440 0.23532 57908.161412 0.000367 0.20146 0.01606 1.00000 0 16.66142 0.54204 15.34240 0.49913 3.35667 0.24430 3.08784 0.22475 57908.162121 0.000341 0.23744 0.01884 1.00000 0 15.52741 0.54379 14.36301 0.50301 3.68681 0.26247 3.41035 0.24279 57908.162824 0.000362 0.21599 0.01732 1.00000 0 15.81048 0.53144 14.51143 0.48777 3.41486 0.24858 3.13724 0.22835 57908.163544 0.000359 0.21872 0.01757 1.00000 0 15.66782 0.53211 14.46724 0.49133 3.42683 0.24941 3.16254 0.23019 57908.164262 0.000359 0.21143 0.01693 1.00000 0 16.16901 0.53879 14.95788 0.49843 3.41860 0.24883 3.16254 0.23019 57908.164980 0.000359 0.20036 0.01596 1.00000 0 17.06046 0.55280 15.78378 0.51144 3.41831 0.24881 3.16254 0.23019 57908.165674 0.000336 0.22405 0.01815 1.00000 0 16.30012 0.55749 15.07949 0.51574 3.65199 0.26827 3.37850 0.24818 57908.166389 0.000379 0.20067 0.01560 0.99237 0 16.82195 0.53625 15.36729 0.48987 3.37562 0.23928 3.08655 0.21875 57908.167164 0.000396 0.20993 0.01680 0.98540 0 15.08972 0.49561 13.86871 0.45546 3.16774 0.23110 2.90919 0.21222 57908.167914 0.000353 0.23437 0.01869 0.99180 0 15.16315 0.52742 13.97994 0.48624 3.55384 0.25496 3.27613 0.23502 57908.168646 0.000379 0.20161 0.01591 0.97710 0 16.79219 0.53350 15.43534 0.49036 3.38552 0.24450 3.11067 0.22464 57908.169410 0.000385 0.19500 0.01556 0.99248 0 16.49626 0.52678 15.17177 0.48448 3.21679 0.23531 2.96013 0.21651 57908.170307 0.000512 0.23293 0.01517 0.98305 0 15.96840 0.44825 14.73054 0.41348 3.71957 0.21850 3.43150 0.20157
