/* ** ** 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 57178.886557 0.000191 0.18537 0.01446 1.00000 0 35.98713 1.10436 32.70015 1.00344 6.67097 0.47850 6.06587 0.43512 57178.886924 0.000177 0.21297 0.01667 1.00000 0 33.33997 1.10516 30.89508 1.02415 7.10043 0.50358 6.57519 0.46633 57178.887286 0.000185 0.20710 0.01622 1.00000 0 32.74886 1.07027 30.47489 0.99596 6.78244 0.48264 6.31145 0.44913 57178.887630 0.000159 0.22911 0.01820 1.00000 0 33.89501 1.17295 31.54547 1.09164 7.76559 0.55520 7.22729 0.51672 57178.887992 0.000203 0.18155 0.01426 1.00000 0 33.54440 1.03031 31.22034 0.95893 6.08996 0.44039 5.66803 0.40988 57178.888397 0.000203 0.18124 0.01413 1.00000 0 33.70042 1.03267 31.36551 0.96112 6.10779 0.43797 5.68461 0.40763 57178.888782 0.000182 0.21023 0.01656 1.00000 0 32.44294 1.07085 30.19607 0.99669 6.82038 0.48782 6.34803 0.45403 57178.889257 0.000292 0.19629 0.01228 0.99091 0 34.16704 0.87191 31.79964 0.81150 6.70677 0.38322 6.24207 0.35667
