/* ** ** 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 58128.096511 0.000472 0.27345 0.00995 1.00000 0 49.28488 0.83286 44.49913 0.75197 13.47718 0.43402 12.17102 0.39199 58128.097468 0.000486 0.26552 0.00965 1.00000 0 49.85405 0.82904 44.33562 0.73722 13.23720 0.42778 11.76942 0.38027 58128.098452 0.000498 0.25568 0.00919 1.00000 0 50.91306 0.83052 45.19514 0.73720 13.01755 0.41700 11.55635 0.37019 58128.099433 0.000483 0.26939 0.00982 1.00000 0 49.79340 0.83308 44.07170 0.73732 13.41378 0.43415 11.86866 0.38412 58128.100414 0.000498 0.26099 0.00943 1.00000 0 49.86127 0.82050 44.29546 0.72888 13.01328 0.41868 11.55746 0.37185 58128.101407 0.000495 0.26444 0.00958 1.00000 0 49.50937 0.82316 43.79940 0.72821 13.09202 0.42139 11.58172 0.37279 58128.102399 0.000498 0.26307 0.00954 1.00000 0 49.36167 0.81940 43.71547 0.72563 12.98540 0.41890 11.49923 0.37093 58128.103389 0.000492 0.26744 0.00973 0.99412 0 48.66306 0.80954 43.71140 0.72710 13.01427 0.42126 11.69621 0.37852 58128.104381 0.000501 0.25694 0.00929 1.00000 0 50.19651 0.81555 44.60659 0.72473 12.89745 0.41674 11.46052 0.37031 58128.105365 0.000483 0.26760 0.00970 1.00000 0 49.88084 0.83252 44.45177 0.74190 13.34801 0.42969 11.89150 0.38279 58128.106725 0.000877 0.26539 0.00710 0.99670 0 50.62917 0.62162 45.11364 0.55387 13.43642 0.31947 11.96948 0.28457
