/* ** ** 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 55043.002777 0.000436 0.30741 0.08866 0.99892 1 2.75987 0.39682 0.69575 0.10003 0.84840 0.21210 0.21354 0.05338 55043.004382 0.000405 0.25041 0.04001 0.97857 0 3.34619 0.23716 2.88790 0.20468 0.83792 0.11999 0.72316 0.10355 55043.005302 0.000515 0.18921 0.02932 0.97191 0 3.52616 0.21649 3.04328 0.18684 0.66719 0.09494 0.57584 0.08194 55043.006196 0.000379 0.25814 0.04121 0.99237 0 3.43974 0.24895 2.96856 0.21485 0.88794 0.12636 0.76631 0.10905 55043.007000 0.000425 0.25251 0.03951 0.98639 0 3.28680 0.23297 2.82732 0.20039 0.82993 0.11578 0.71467 0.09970 55043.007854 0.000428 0.21802 0.03425 0.98649 0 3.62649 0.24140 3.12972 0.20833 0.79063 0.11251 0.68233 0.09710 55043.008809 0.000527 0.19278 0.02925 0.97802 0 3.54817 0.21606 3.06228 0.18648 0.68401 0.09507 0.59036 0.08205 55043.009911 0.000576 0.19517 0.03036 0.97990 0 3.03258 0.19040 2.61752 0.16434 0.59187 0.08423 0.51087 0.07270 55043.010988 0.000501 0.20469 0.03166 0.98266 0 3.38377 0.21615 2.92035 0.18655 0.69263 0.09758 0.59778 0.08422 55043.012336 0.000848 0.20612 0.02459 0.97686 0 3.36196 0.16587 2.90183 0.14317 0.69296 0.07527 0.59812 0.06496
