/* ** ** 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 59654.230016 0.000749 0.26330 0.02124 0.96139 0 7.28418 0.26665 6.01745 0.22023 1.91789 0.13790 1.58810 0.11417 59654.231422 0.000657 0.31017 0.02557 0.96916 0 6.97291 0.28019 5.82281 0.23398 2.16276 0.15570 1.80615 0.13003 59654.233066 0.000987 0.28149 0.01900 0.97426 0 7.40509 0.23328 6.19603 0.19519 2.08449 0.12440 1.74424 0.10409 59654.701220 0.000885 0.28946 0.02196 0.97193 0 7.69019 0.27838 5.32966 0.19273 2.22598 0.14837 1.54531 0.10289 59654.971548 0.000599 0.32593 0.02694 0.98551 0 7.01052 0.28730 5.98619 0.24527 2.28496 0.16399 1.95306 0.14013 59654.972769 0.000622 0.28395 0.02293 0.99070 0 7.61084 0.29279 6.62277 0.25478 2.16112 0.15343 1.88069 0.13352 59654.974537 0.001146 0.29529 0.01768 0.98485 0 7.39614 0.21212 6.44153 0.18474 2.18403 0.11482 1.90204 0.10000
