/* ** ** 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 60002.073611 0.000810 0.11128 0.00846 0.99286 0 14.29407 0.34237 12.75116 0.30538 1.59069 0.11477 1.42169 0.10253 60002.075229 0.000807 0.10929 0.00840 0.98566 0 14.67478 0.34905 13.03183 0.30992 1.60385 0.11721 1.42402 0.10407 60002.076982 0.000946 0.09637 0.00733 0.98471 0 14.33027 0.32298 12.68634 0.28589 1.38097 0.10028 1.22179 0.08870 60002.079254 0.001319 0.09913 0.00626 0.97783 0 14.51644 0.27311 12.94180 0.24345 1.43905 0.08669 1.28305 0.07729 60002.139185 0.000382 0.12352 0.01876 0.95455 0 8.90627 0.44558 6.38151 0.31924 1.10012 0.15771 0.78669 0.11273 60002.139926 0.000359 0.08562 0.01644 0.97581 0 8.64877 0.46331 6.04422 0.32346 0.74047 0.13656 0.51257 0.09445
