/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 59570.088167 0.000446 0.32008 0.02666 0.98052 0 9.72878 0.39652 8.16083 0.33203 3.11395 0.22624 2.60543 0.18915 59570.088995 0.000382 0.35891 0.03039 0.98485 0 9.81026 0.42727 8.43168 0.36721 3.52103 0.25562 3.02630 0.21971 59570.089773 0.000396 0.34760 0.02899 0.99270 0 9.89838 0.42275 8.39990 0.35860 3.44063 0.24650 2.91944 0.20917 59570.090604 0.000434 0.29699 0.02454 1.00000 0 10.29579 0.40643 8.83162 0.34863 3.05777 0.22200 2.62280 0.19042 59570.091449 0.000411 0.33935 0.02878 0.99296 0 9.54908 0.40600 8.18864 0.34816 3.24049 0.23775 2.77872 0.20388 59570.092305 0.000446 0.32547 0.02660 0.98052 0 9.51011 0.38998 8.15245 0.33431 3.09528 0.21887 2.65342 0.18763 59570.093144 0.000394 0.35611 0.03013 0.97794 0 9.69470 0.41652 8.31089 0.35707 3.45238 0.25165 2.95948 0.21571 59570.093949 0.000411 0.33561 0.02789 0.98592 0 9.92539 0.41329 8.45452 0.35206 3.33103 0.23959 2.83739 0.20411 59570.094773 0.000414 0.36279 0.03014 0.98601 0 9.18398 0.39903 7.87742 0.34225 3.33188 0.23596 2.85718 0.20234 59570.095650 0.000463 0.27724 0.02238 0.99375 0 10.60471 0.40316 9.05317 0.34415 2.94006 0.20932 2.50852 0.17855 59570.096660 0.000547 0.33098 0.02424 0.98942 0 9.64071 0.35300 8.26610 0.30266 3.19086 0.20234 2.73592 0.17350
