/* ** ** 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 58252.294879 0.000379 0.18601 0.01460 0.99237 0 18.14894 0.55915 16.30968 0.50248 3.37588 0.24371 3.03586 0.21915 58252.295649 0.000391 0.18055 0.01409 0.99259 0 18.12609 0.55455 16.37445 0.50096 3.27264 0.23502 2.95644 0.21232 58252.296422 0.000382 0.18601 0.01476 0.96970 0 18.39949 0.56502 16.47411 0.50588 3.42252 0.25035 3.06376 0.22405 58252.297209 0.000405 0.17811 0.01381 0.99286 0 17.78103 0.53699 16.06283 0.48510 3.16691 0.22626 2.86089 0.20439 58252.297993 0.000379 0.18438 0.01453 0.98473 0 18.47957 0.56831 16.53533 0.50848 3.40730 0.24725 3.04775 0.22116 58252.298739 0.000367 0.19614 0.01526 0.99213 0 17.96371 0.56906 16.15004 0.51161 3.52336 0.25043 3.16798 0.22517 58252.299529 0.000422 0.16870 0.01309 0.99315 0 17.93192 0.52753 16.19603 0.47647 3.02509 0.21725 2.73216 0.19621 58252.300363 0.000411 0.16474 0.01297 0.99296 0 19.00944 0.55354 16.88988 0.49176 3.13155 0.22906 2.78128 0.20339 58252.301161 0.000388 0.18472 0.01449 0.98507 0 18.08061 0.55600 16.18119 0.49759 3.33985 0.24110 2.98986 0.21583 58252.301989 0.000440 0.16729 0.01311 0.99342 0 17.28979 0.51022 15.55916 0.45914 2.89245 0.20991 2.60371 0.18894 58252.302808 0.000379 0.18004 0.01411 1.00000 0 18.99210 0.58047 16.83202 0.51447 3.41926 0.24686 3.03181 0.21885 58252.303586 0.000399 0.18564 0.01446 0.99275 0 17.38302 0.53813 15.63203 0.48393 3.22692 0.23057 2.90266 0.20738 58252.304419 0.000434 0.18807 0.01388 0.98000 0 18.27382 0.52974 16.36633 0.47437 3.43670 0.23335 3.07661 0.20888
