/* ** ** 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 57160.923919 0.000272 0.17899 0.01410 0.96809 0 26.41371 0.79094 24.13869 0.72278 4.72778 0.34450 4.31841 0.31470 57160.924489 0.000298 0.17304 0.01334 0.99029 0 24.68369 0.73112 22.65937 0.67116 4.27117 0.30407 3.92059 0.27911 57160.925047 0.000260 0.18201 0.01444 1.00000 0 26.15753 0.80751 23.85495 0.73641 4.76104 0.34784 4.34413 0.31742 57160.925609 0.000301 0.15679 0.01212 1.00000 0 26.64336 0.75730 24.34546 0.69197 4.17745 0.30021 3.81856 0.27439 57160.926187 0.000278 0.17063 0.01315 0.98958 0 26.85649 0.79262 24.66979 0.72809 4.58257 0.32624 4.20948 0.29968 57160.926746 0.000281 0.18331 0.01411 0.98969 0 25.10548 0.76412 22.91186 0.69733 4.60214 0.32534 4.20092 0.29694 57160.927307 0.000281 0.17054 0.01317 0.98969 0 26.45517 0.78102 24.30358 0.71750 4.51171 0.32201 4.14476 0.29582 57160.927903 0.000315 0.15454 0.01192 0.99083 0 26.07206 0.73112 23.95186 0.67166 4.02907 0.28937 3.70141 0.26584 57160.928522 0.000304 0.15523 0.01191 0.99048 0 27.06385 0.76223 24.79318 0.69826 4.20124 0.29976 3.85114 0.27475 57160.929107 0.000281 0.16994 0.01348 0.98969 0 26.11683 0.77686 23.92152 0.71157 4.43822 0.32644 4.06464 0.29901 57160.929703 0.000315 0.14957 0.01151 0.99083 0 26.97073 0.74704 24.75109 0.68555 4.03393 0.28972 3.70141 0.26584 57160.930328 0.000310 0.16044 0.01245 1.00000 0 25.16928 0.72785 23.01689 0.66554 4.03818 0.29091 3.69278 0.26604 57160.930915 0.000278 0.16975 0.01345 1.00000 0 26.19755 0.78610 24.06814 0.72221 4.44697 0.32625 4.08551 0.29973 57160.931442 0.000249 0.20458 0.01612 1.00000 0 24.53368 0.80158 22.53745 0.73636 5.01912 0.35991 4.61061 0.33061 57160.931963 0.000272 0.19427 0.01517 0.98936 0 24.33044 0.76231 22.21753 0.69610 4.72673 0.33798 4.31330 0.30836 57160.932504 0.000269 0.18611 0.01457 1.00000 0 24.97218 0.77441 22.94481 0.71154 4.64750 0.33396 4.27022 0.30685 57160.933077 0.000304 0.16787 0.01308 1.00000 0 24.52886 0.72504 22.40150 0.66216 4.11769 0.29673 3.76311 0.27111 57160.933693 0.000312 0.15101 0.01161 0.99074 0 26.70988 0.74171 24.53999 0.68145 4.03336 0.28922 3.70572 0.26573 57160.934341 0.000336 0.14411 0.01094 1.00000 0 26.25631 0.71257 23.99207 0.65114 3.78380 0.26814 3.45936 0.24514 57160.935033 0.000356 0.17112 0.01202 1.00000 0 24.95980 0.67015 22.93112 0.61569 4.27118 0.27717 3.92403 0.25464
