/* ** ** 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 56523.032832 0.000388 0.24532 0.03443 0.99254 0 4.77604 0.29580 3.98874 0.24698 1.17163 0.14755 0.97411 0.12270 56523.034285 0.001065 0.26906 0.02184 0.97554 0 4.91764 0.18216 4.06992 0.15075 1.32315 0.09557 1.09530 0.07911 56523.036087 0.000738 0.24457 0.02506 0.97647 0 4.81216 0.21659 3.98775 0.17948 1.17693 0.10832 0.97626 0.08985 56523.037861 0.001036 0.31040 0.02545 0.95531 0 4.49689 0.17799 3.72670 0.14751 1.39582 0.10021 1.15597 0.08299 56523.039965 0.001068 0.25099 0.01999 0.97561 0 5.34969 0.19163 4.41007 0.15796 1.34271 0.09553 1.10705 0.07875 56523.042065 0.001033 0.29060 0.02350 0.98599 0 4.79201 0.18360 3.91741 0.15008 1.39254 0.09917 1.13754 0.08100 56523.043417 0.000318 0.25140 0.04018 0.97273 0 4.44358 0.31547 3.68329 0.26149 1.11714 0.15994 0.92618 0.13258 56523.044073 0.000339 0.24212 0.03587 0.96581 0 5.13525 0.33316 4.15532 0.26957 1.24336 0.16558 1.00582 0.13393
