/* ** ** 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 59455.876114 0.000373 0.25761 0.04054 0.97674 0 3.65584 0.26248 3.14772 0.22600 0.94178 0.13188 0.81087 0.11355 59455.876794 0.000307 0.26240 0.04110 0.99057 0 4.42634 0.32223 3.77466 0.27477 1.16147 0.16108 0.99213 0.13758 59455.877575 0.000475 0.29219 0.03820 0.98171 0 3.87729 0.24341 3.33115 0.20912 1.13292 0.12993 0.97317 0.11161 59455.878363 0.000312 0.22754 0.03656 0.99074 0 4.70988 0.32884 4.02462 0.28099 1.07167 0.15511 0.91699 0.13274 59455.878988 0.000312 0.25450 0.03970 0.99074 0 4.48621 0.31880 3.86205 0.27445 1.14176 0.15856 0.98273 0.13647 59455.879630 0.000330 0.24289 0.03875 0.97368 0 4.31058 0.30422 3.69181 0.26055 1.04701 0.14979 0.89317 0.12779 59455.880970 0.001010 0.29392 0.02401 0.99140 0 4.54938 0.17853 3.89254 0.15275 1.33717 0.09580 1.14467 0.08200 59455.882607 0.000628 0.24422 0.02707 0.95392 0 4.75353 0.23360 4.05485 0.19926 1.16091 0.11537 0.98940 0.09831 59455.883571 0.000336 0.20973 0.03284 0.98276 0 4.84531 0.31695 4.16812 0.27265 1.01619 0.14454 0.87416 0.12434 59455.885081 0.001175 0.25733 0.02054 0.97291 0 4.60957 0.16711 3.92195 0.14217 1.18620 0.08437 1.00916 0.07177 59455.886583 0.000327 0.25965 0.03978 0.96460 0 4.50452 0.31686 3.83446 0.26973 1.16959 0.15917 0.99248 0.13506 59455.887538 0.000628 0.21364 0.02546 0.97696 0 4.54596 0.22938 3.82739 0.19310 0.97121 0.10483 0.81729 0.08821
