/* ** ** 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 57780.186957 0.000457 0.21000 0.01716 0.99367 0 19.66034 0.65625 12.04152 0.39748 4.12860 0.30794 2.47067 0.18306 57780.187918 0.000503 0.17857 0.01452 0.97126 0 23.54352 0.72528 12.74169 0.39194 4.20419 0.31626 2.27365 0.17074 57780.188948 0.000527 0.17754 0.01394 0.97802 0 23.37570 0.70933 12.49950 0.37933 4.15017 0.30058 2.22119 0.16087 57780.189917 0.000443 0.23648 0.01911 0.98039 0 21.29191 0.74992 11.15203 0.39273 5.03507 0.36618 2.63701 0.19176 57780.190864 0.000503 0.20296 0.01643 0.95977 0 21.65982 0.70668 11.43626 0.37309 4.39603 0.32567 2.32273 0.17209 57780.191923 0.000556 0.17621 0.01388 0.98438 0 22.36703 0.68171 11.79544 0.35954 3.94123 0.28624 2.08132 0.15114 57780.192961 0.000483 0.21667 0.01778 0.98204 0 20.53968 0.70140 10.85219 0.37054 4.45042 0.33209 2.35409 0.17559 57780.193986 0.000541 0.19338 0.01569 0.96257 0 21.23382 0.67739 11.08836 0.35367 4.10617 0.30630 2.14484 0.15999 57780.195025 0.000498 0.21532 0.01688 0.97674 0 21.52616 0.71148 11.13989 0.36814 4.63508 0.32960 2.39898 0.17059 57780.196084 0.000561 0.17389 0.01378 0.98969 0 22.62438 0.69142 11.72637 0.35835 3.93426 0.28766 2.03930 0.14908 57780.197611 0.000966 0.18996 0.01105 0.98802 0 22.40962 0.51873 11.57504 0.26791 4.25694 0.22729 2.20139 0.11753
