/* ** ** 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 57404.133856 0.000391 0.16457 0.01327 0.98519 0 31.44593 0.95926 17.95307 0.52668 5.17504 0.38633 2.98679 0.21485 57404.134611 0.000365 0.16108 0.01266 0.97619 0 33.14110 0.95499 19.83387 0.57003 5.33837 0.39039 3.18392 0.23267 57404.135424 0.000448 0.14818 0.01161 1.00000 0 32.44699 0.91796 17.02177 0.48156 4.80793 0.35140 2.52660 0.18464 57404.136373 0.000501 0.13222 0.01013 0.99422 0 32.17905 0.84698 17.44888 0.45901 4.25483 0.30622 2.30956 0.16613 57404.137294 0.000420 0.15070 0.01157 1.00000 0 33.53199 0.93966 18.21141 0.51024 5.05316 0.36127 2.75209 0.19667 57404.138141 0.000428 0.14017 0.01094 1.00000 0 34.83056 0.94872 18.86185 0.51357 4.88225 0.35696 2.64610 0.19337 57404.138949 0.000379 0.15817 0.01214 1.00000 0 34.71785 0.99422 19.24204 0.55087 5.49141 0.39087 3.04472 0.21671 57404.139718 0.000391 0.15720 0.01214 1.00000 0 33.84734 0.97208 18.64210 0.53515 5.32065 0.38155 2.94111 0.21072 57404.140502 0.000394 0.15486 0.01191 0.99265 0 34.43866 0.97378 19.08275 0.53921 5.33327 0.38138 2.95595 0.21124 57404.141298 0.000402 0.15282 0.01192 0.98561 0 34.10173 0.96698 18.78362 0.53249 5.21146 0.37866 2.87176 0.20848 57404.142042 0.000341 0.16733 0.01341 1.00000 0 34.80825 1.04301 19.60096 0.58710 5.82441 0.43296 3.28982 0.24457 57404.142780 0.000396 0.14295 0.01096 0.98540 0 35.85231 0.96791 20.64688 0.55720 5.12515 0.36771 2.95739 0.21218 57404.143506 0.000330 0.17445 0.01379 0.99123 0 35.91468 1.08959 19.98601 0.60604 6.26542 0.45725 3.48341 0.25388 57404.144192 0.000356 0.15781 0.01233 0.99187 0 35.00669 1.00980 20.41803 0.58895 5.52437 0.40115 3.22485 0.23411 57404.145190 0.000642 0.16650 0.00943 0.99099 0 34.97486 0.74641 20.46388 0.43656 5.82330 0.30557 3.40187 0.17842
