/* ** ** 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 57426.451598 0.000521 0.13084 0.00994 1.00000 0 18.24199 0.47194 16.88244 0.43677 2.38682 0.17059 2.20876 0.15786 57426.452714 0.000596 0.11810 0.00908 0.97573 0 18.02815 0.44351 16.59132 0.40813 2.12916 0.15506 1.95722 0.14255 57426.453831 0.000521 0.12976 0.00996 0.98889 0 18.66020 0.48173 17.09635 0.44132 2.42131 0.17495 2.21622 0.16011 57426.454870 0.000518 0.13176 0.01002 0.98883 0 18.51670 0.48039 17.03741 0.44202 2.43982 0.17439 2.24620 0.16054 57426.455990 0.000602 0.11920 0.00902 0.99038 0 17.58354 0.43459 16.15725 0.39930 2.09599 0.14985 1.92999 0.13794 57426.457092 0.000501 0.14586 0.01124 0.98266 0 17.37860 0.47394 15.98947 0.43603 2.53477 0.18265 2.33230 0.16806 57426.458111 0.000518 0.13171 0.01022 0.99441 0 18.11283 0.47613 16.66505 0.43805 2.38570 0.17425 2.19886 0.16058 57426.459176 0.000547 0.12752 0.00972 0.98942 0 18.14812 0.46229 16.81956 0.42845 2.31418 0.16634 2.14415 0.15412 57426.460232 0.000509 0.14478 0.01102 0.98295 0 17.35709 0.47062 15.94072 0.43218 2.51298 0.17867 2.30706 0.16401 57426.461288 0.000547 0.12146 0.00920 1.00000 0 18.75052 0.47041 17.33105 0.43477 2.27739 0.16276 2.10358 0.15035 57426.462521 0.000686 0.14395 0.00932 0.98734 0 17.61860 0.40549 16.32335 0.37566 2.53616 0.15354 2.34774 0.14213
