/* ** ** 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 57477.973801 0.000304 0.15710 0.01212 1.00000 0 26.99431 0.76387 24.19078 0.68454 4.24086 0.30446 3.80149 0.27286 57477.974426 0.000321 0.14886 0.01158 0.99099 0 26.71261 0.74556 24.03495 0.67081 3.97635 0.28880 3.57555 0.25972 57477.975063 0.000315 0.14613 0.01142 1.00000 0 28.09540 0.77593 24.86350 0.68666 4.10567 0.30000 3.62975 0.26511 57477.975679 0.000301 0.16121 0.01252 1.00000 0 26.48930 0.76619 23.81428 0.68885 4.27023 0.30773 3.83962 0.27672 57477.976281 0.000301 0.15618 0.01227 0.99038 0 27.19155 0.78164 24.33113 0.69945 4.24674 0.31063 3.80069 0.27795 57477.976909 0.000327 0.14279 0.01121 0.99115 0 27.60326 0.75672 24.38985 0.66855 3.94158 0.29000 3.47886 0.25614 57477.977525 0.000289 0.15606 0.01223 1.00000 0 28.50483 0.81532 25.19479 0.72056 4.44845 0.32456 3.93475 0.28698 57477.978150 0.000336 0.14151 0.01098 1.00000 0 26.66689 0.72694 23.92351 0.65215 3.77356 0.27416 3.39061 0.24629 57477.978787 0.000301 0.16801 0.01311 0.98077 0 25.67332 0.76270 23.01811 0.68387 4.31332 0.31125 3.87402 0.27951 57477.979395 0.000307 0.15683 0.01232 0.99057 0 26.70442 0.76414 23.79637 0.68091 4.18804 0.30626 3.72830 0.27265 57477.980049 0.000347 0.13827 0.01056 1.00000 0 26.92634 0.72228 24.03671 0.64469 3.72303 0.26610 3.32493 0.23768 57477.980702 0.000307 0.15716 0.01210 1.00000 0 26.93576 0.76847 23.96965 0.68380 4.23316 0.30259 3.76408 0.26907 57477.981310 0.000301 0.15266 0.01183 0.99038 0 28.47585 0.80690 25.11391 0.71165 4.34708 0.31360 3.83640 0.27680 57477.981978 0.000367 0.12626 0.01010 0.98425 0 27.08699 0.70287 24.21179 0.62829 3.42002 0.25864 3.05821 0.23138 57477.982696 0.000350 0.13033 0.00995 0.99174 0 28.66550 0.74130 25.48369 0.65899 3.73601 0.26821 3.32630 0.23875 57477.983367 0.000321 0.14671 0.01118 1.00000 0 27.78312 0.76557 24.61625 0.67823 4.07619 0.28948 3.61109 0.25641 57477.984201 0.000512 0.15054 0.00922 0.98870 0 27.08393 0.59338 24.15161 0.52908 4.07735 0.23318 3.63547 0.20792
