/* ** ** 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 56000.141297 0.000466 0.32865 0.02737 1.00000 0 8.26163 0.34128 7.44239 0.30742 2.71521 0.19638 2.44427 0.17677 56000.142223 0.000460 0.33190 0.02750 0.98113 0 8.58072 0.35381 7.63088 0.31461 2.84795 0.20468 2.53569 0.18220 56000.143160 0.000477 0.32753 0.02674 0.98788 0 8.52497 0.34721 7.51073 0.30591 2.79216 0.19759 2.46411 0.17436 56000.144144 0.000506 0.30498 0.02512 0.99429 0 8.43563 0.33539 7.46425 0.29678 2.57267 0.18560 2.27317 0.16397 56000.145183 0.000532 0.31250 0.02532 0.97283 0 8.09522 0.31993 7.15767 0.28287 2.52979 0.17889 2.23836 0.15828 56000.146245 0.000530 0.30143 0.02487 0.97814 0 8.29412 0.32452 7.30747 0.28590 2.50011 0.18162 2.20377 0.16008 56000.147301 0.000527 0.30399 0.02502 0.98352 0 8.21875 0.32578 7.25996 0.28775 2.49839 0.18019 2.20967 0.15939 56000.148345 0.000518 0.29985 0.02441 1.00000 0 8.44379 0.33242 7.45689 0.29355 2.53185 0.18042 2.23796 0.15947 56000.149364 0.000501 0.31076 0.02560 0.98844 0 8.44330 0.33501 7.48815 0.29708 2.62380 0.18947 2.32455 0.16788 56000.150608 0.000744 0.33899 0.02249 0.99611 0 8.08850 0.26917 7.17857 0.23889 2.74193 0.15740 2.43303 0.13968
