/* ** ** 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 58498.074105 0.000284 0.19711 0.01540 1.00000 0 23.04274 0.73312 20.60252 0.65549 4.54185 0.32409 4.06083 0.28975 58498.074699 0.000310 0.18213 0.01427 0.98131 0 23.42451 0.71475 20.69799 0.63155 4.26636 0.30776 3.77052 0.27203 58498.075361 0.000353 0.16310 0.01255 0.99180 0 22.68915 0.65539 20.30016 0.58639 3.70064 0.26390 3.31086 0.23611 58498.076006 0.000292 0.18516 0.01457 0.99010 0 23.78175 0.73562 21.27279 0.65801 4.40344 0.31852 3.93902 0.28493 58498.076600 0.000301 0.17379 0.01373 1.00000 0 24.19613 0.73193 21.64463 0.65474 4.20502 0.30696 3.76150 0.27458 58498.077201 0.000301 0.18841 0.01481 1.00000 0 22.54665 0.70960 20.17174 0.63485 4.24805 0.30588 3.80053 0.27366 58498.077824 0.000321 0.18141 0.01410 0.99099 0 22.32639 0.68036 19.97585 0.60874 4.05019 0.28957 3.62374 0.25908 58498.078443 0.000298 0.18947 0.01502 1.00000 0 22.48322 0.71104 20.11469 0.63613 4.25987 0.30954 3.81115 0.27694 58498.079027 0.000286 0.19175 0.01486 1.00000 0 23.62902 0.74237 21.14065 0.66419 4.53090 0.32103 4.05371 0.28722 58498.079597 0.000284 0.19194 0.01503 0.98980 0 23.79868 0.75030 21.30280 0.67161 4.56781 0.32741 4.08874 0.29307 58498.080176 0.000295 0.19886 0.01559 0.99020 0 22.22379 0.70713 19.87903 0.63253 4.41948 0.31659 3.95308 0.28318 58498.080810 0.000339 0.16782 0.01306 0.99145 0 22.87700 0.67074 20.47360 0.60028 3.83923 0.27680 3.43585 0.24771 58498.081429 0.000281 0.20124 0.01590 1.00000 0 22.66500 0.73081 20.28213 0.65398 4.56103 0.32906 4.08150 0.29446 58498.081984 0.000275 0.21026 0.01653 1.00000 0 22.60021 0.74414 20.22069 0.66579 4.75200 0.33932 4.25177 0.30361 58498.082534 0.000275 0.20674 0.01628 1.00000 0 22.67652 0.74716 20.29545 0.66870 4.68817 0.33518 4.19591 0.29999 58498.083090 0.000281 0.20898 0.01645 1.00000 0 21.93368 0.72790 19.63139 0.65150 4.58371 0.32706 4.10269 0.29274 58498.083686 0.000315 0.16708 0.01316 0.99083 0 24.22257 0.71773 21.67987 0.64239 4.04703 0.29543 3.62218 0.26441 58498.084291 0.000289 0.19618 0.01544 1.00000 0 22.62443 0.72721 20.25064 0.65091 4.43839 0.31876 3.97258 0.28531 58498.084985 0.000405 0.19872 0.01328 1.00000 0 21.98240 0.60127 19.67937 0.53827 4.36844 0.26642 3.91077 0.23851
