/* ** ** 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 56089.046669 0.000579 0.38474 0.03290 0.98500 0 7.26923 0.32666 5.21294 0.23195 2.79675 0.20351 2.00203 0.14440 56089.047992 0.000744 0.28612 0.02314 0.96887 0 7.35879 0.27924 5.58617 0.21193 2.10548 0.15035 1.59652 0.11401 56089.049389 0.000654 0.32613 0.02706 0.98673 0 7.12724 0.29178 5.43675 0.22257 2.32441 0.16777 1.77291 0.12797 56089.050723 0.000680 0.30261 0.02509 0.97872 0 7.35620 0.29129 5.62354 0.22267 2.22609 0.16217 1.70116 0.12393 56089.051988 0.000584 0.34045 0.02844 0.98020 0 7.62402 0.31826 5.83233 0.24347 2.59559 0.18785 1.98665 0.14377 56089.053246 0.000674 0.30219 0.02467 0.98712 0 7.49010 0.29620 5.71848 0.22613 2.26343 0.16166 1.72841 0.12343 56089.054511 0.000584 0.35906 0.03073 0.99010 0 7.07798 0.30586 5.40033 0.23336 2.54144 0.18778 1.94024 0.14335 56089.055714 0.000619 0.35228 0.02939 0.97196 0 7.10766 0.30093 5.39914 0.22859 2.50391 0.17998 1.90118 0.13667 56089.056964 0.000631 0.33002 0.02678 0.98624 0 7.60629 0.30789 5.77467 0.23374 2.51019 0.17659 1.90490 0.13400
