/* ** ** 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 56054.934128 0.000362 0.18455 0.01447 0.97600 0 19.94378 0.61058 17.51358 0.53615 3.68071 0.26564 3.23293 0.23335 56054.934895 0.000405 0.16596 0.01318 0.97857 0 19.47369 0.56955 17.12411 0.50080 3.23182 0.23856 2.83883 0.20951 56054.935778 0.000477 0.13579 0.01064 0.98182 0 20.37179 0.54083 17.64861 0.46853 2.76623 0.20389 2.39609 0.17658 56054.936709 0.000454 0.14512 0.01129 0.99363 0 19.82928 0.54493 17.28869 0.47507 2.87761 0.20945 2.51229 0.18284 56054.937661 0.000498 0.13092 0.01000 0.98837 0 20.12334 0.52078 17.77257 0.45995 2.63446 0.18936 2.32745 0.16730 56054.938636 0.000477 0.14814 0.01135 0.97576 0 19.00144 0.51883 16.65300 0.45470 2.81480 0.20150 2.46532 0.17648 56054.939586 0.000472 0.14629 0.01118 0.98773 0 19.30685 0.52568 16.95752 0.46164 2.82447 0.20166 2.47777 0.17692 56054.940517 0.000460 0.14371 0.01114 0.99371 0 19.82629 0.53899 17.33601 0.47126 2.84931 0.20686 2.49317 0.18098 56054.941420 0.000443 0.14869 0.01138 1.00000 0 20.18349 0.55636 17.53267 0.48326 3.00110 0.21426 2.60732 0.18617 56054.942250 0.000388 0.16988 0.01322 0.98507 0 20.22759 0.59595 17.66696 0.52052 3.43620 0.24740 3.00318 0.21621 56054.943121 0.000483 0.13082 0.01007 0.99401 0 20.65026 0.53678 18.09210 0.47026 2.70151 0.19581 2.36848 0.17167 56054.944351 0.000747 0.14627 0.00877 0.98837 0 20.06521 0.42796 17.39401 0.37097 2.93497 0.16436 2.54447 0.14249
