/* ** ** 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 57184.893476 0.000425 0.14386 0.01099 0.99320 0 20.63872 0.55889 18.94675 0.51305 2.96906 0.21202 2.72467 0.19455 57184.894335 0.000434 0.14413 0.01104 0.99333 0 20.22097 0.55058 18.55987 0.50528 2.91435 0.20858 2.67364 0.19134 57184.895151 0.000382 0.15413 0.01189 1.00000 0 21.34839 0.60348 19.46948 0.55036 3.29047 0.23610 3.00280 0.21545 57184.895927 0.000394 0.15991 0.01228 1.00000 0 19.86488 0.56912 18.38383 0.52668 3.17654 0.22624 2.93974 0.20937 57184.896665 0.000344 0.18177 0.01405 0.99160 0 20.28960 0.61769 18.62887 0.56707 3.68803 0.26206 3.38334 0.24040 57184.897793 0.000784 0.15598 0.00862 0.99263 0 20.03588 0.40695 18.48190 0.37537 3.12516 0.16065 2.88204 0.14812
