/* ** ** 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 59704.020971 0.000709 0.12903 0.00977 0.99592 0 14.61013 0.37465 12.66086 0.32465 1.88521 0.13436 1.63243 0.11631 59704.022319 0.000639 0.14669 0.01132 0.99548 0 14.03072 0.38702 12.22751 0.33726 2.05813 0.14833 1.79446 0.12933 59704.023552 0.000593 0.15311 0.01188 0.98049 0 14.66660 0.41099 12.78390 0.35823 2.24567 0.16247 1.95824 0.14168 59704.025276 0.001131 0.13371 0.00803 0.97972 0 14.35512 0.29462 12.49810 0.25649 1.91943 0.10833 1.67075 0.09429 59704.086813 0.000570 0.14473 0.01130 0.97970 0 15.32351 0.41850 13.97985 0.38182 2.21776 0.16223 2.02465 0.14807 59704.088109 0.000726 0.12186 0.00914 0.99203 0 14.36680 0.35879 13.19677 0.32957 1.75069 0.12379 1.60910 0.11378 59704.089903 0.001068 0.13379 0.00790 0.99458 0 14.69501 0.29726 13.53642 0.27382 1.96597 0.10911 1.81097 0.10050
