/* ** ** 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 55649.215472 0.000587 0.11610 0.00895 0.99507 0 18.13025 0.44458 16.69472 0.40937 2.10498 0.15380 1.93885 0.14167 55649.216620 0.000561 0.12484 0.00964 0.98969 0 17.87914 0.45304 16.51445 0.41846 2.23211 0.16286 2.06174 0.15043 55649.217792 0.000611 0.11950 0.00933 0.97156 0 17.14818 0.42601 15.83960 0.39350 2.04926 0.15173 1.89288 0.14015 55649.219034 0.000631 0.11621 0.00879 0.96789 0 17.53083 0.42467 16.19273 0.39226 2.03730 0.14596 1.88180 0.13482 55649.220243 0.000579 0.12701 0.00987 0.99500 0 16.83623 0.43378 15.50311 0.39942 2.13841 0.15686 1.96908 0.14444 55649.221354 0.000532 0.13383 0.01033 0.99457 0 17.39184 0.45796 16.06493 0.42302 2.32759 0.16896 2.15001 0.15607 55649.222431 0.000544 0.13524 0.01031 0.96809 0 17.59236 0.45699 16.14981 0.41948 2.37921 0.17044 2.18164 0.15630 55649.223562 0.000587 0.12725 0.00962 1.00000 0 16.90249 0.43248 15.41768 0.39446 2.15092 0.15309 1.96484 0.13985 55649.224751 0.000602 0.12322 0.00947 0.97596 0 17.13860 0.42746 15.81951 0.39454 2.11176 0.15350 1.94904 0.14166 55649.225868 0.000515 0.14824 0.01094 0.98315 0 18.45121 0.48342 16.88790 0.44243 2.73521 0.18869 2.50128 0.17250
