/* ** ** 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 58719.021629 0.000495 0.14235 0.03405 0.95322 0 2.06786 0.17565 1.72897 0.14687 0.29435 0.06582 0.24581 0.05496 58719.022442 0.000318 0.26576 0.06910 0.94545 0 1.67984 0.19658 1.40055 0.16389 0.44643 0.10365 0.37233 0.08647 58719.023435 0.000674 0.22772 0.03572 0.97425 0 2.29924 0.15590 1.93779 0.13137 0.52358 0.07405 0.44126 0.06240 58719.024451 0.000341 0.20343 0.05057 0.95763 0 2.03727 0.20894 1.72341 0.17675 0.41444 0.09384 0.35061 0.07938 58719.025324 0.000532 0.14268 0.03425 0.96196 0 1.87548 0.16375 1.58652 0.13852 0.26759 0.05983 0.22637 0.05062 58719.026178 0.000321 0.18337 0.04527 0.99099 0 2.32194 0.22860 1.96417 0.19338 0.42578 0.09640 0.36017 0.08155 58719.026922 0.000422 0.19284 0.04721 0.95205 0 1.76691 0.17618 1.49506 0.14907 0.34073 0.07619 0.28825 0.06445 58719.027659 0.000315 0.20118 0.04961 0.99083 0 2.17933 0.22655 1.84389 0.19168 0.43844 0.09804 0.37099 0.08296 58719.028282 0.000307 0.21888 0.05428 0.95283 0 2.14229 0.22962 1.81237 0.19425 0.46891 0.10485 0.39670 0.08870 58719.029225 0.000637 0.20832 0.03811 0.91481 0 2.13987 0.16742 1.81009 0.14162 0.44577 0.07372 0.37708 0.06236
