/* ** ** 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 56786.063450 0.000613 0.33200 0.02745 0.97642 0 10.32917 0.42232 5.84911 0.23882 3.42930 0.24638 1.92468 0.13810 56786.064732 0.000668 0.32309 0.02675 0.96970 0 9.82116 0.39917 5.44851 0.22144 3.17307 0.22888 1.76072 0.12699 56786.066086 0.000686 0.32716 0.02716 0.97468 0 9.37028 0.38420 5.23139 0.21449 3.06553 0.22126 1.71152 0.12353 56786.067423 0.000651 0.38244 0.03236 0.96889 0 8.53262 0.38081 4.74459 0.21174 3.26325 0.23458 1.81397 0.13040 56786.068679 0.000605 0.37246 0.03155 0.98086 0 9.29010 0.40908 5.15382 0.22696 3.46023 0.25041 1.91882 0.13886 56786.069966 0.000677 0.35300 0.03003 0.97863 0 8.66148 0.36949 4.80442 0.20495 3.05754 0.22503 1.69492 0.12472 56786.071303 0.000660 0.32656 0.02705 0.99123 0 9.65975 0.39747 5.35952 0.22052 3.15445 0.22677 1.74976 0.12579 56786.073123 0.001160 0.33009 0.02048 0.99501 0 9.79996 0.30351 5.42656 0.16806 3.23487 0.17391 1.79096 0.09629
