/* ** ** 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 57500.066781 0.000334 0.36334 0.09217 0.95652 1 4.98106 0.64431 1.05096 0.13592 1.80984 0.39496 0.38182 0.08332 57500.067478 0.000363 0.33338 0.08732 0.96000 1 4.75134 0.63397 0.99382 0.13259 1.58401 0.35700 0.33096 0.07457 57500.068262 0.000421 0.24495 0.05991 1.00000 1 5.62918 0.62136 1.17961 0.13020 1.37888 0.30092 0.28966 0.06321 57500.069018 0.000334 0.32744 0.08502 0.95652 1 5.17886 0.66814 1.10132 0.14208 1.69575 0.38209 0.36105 0.08135 57500.069686 0.000334 0.30148 0.07566 0.95652 1 5.89633 0.71410 1.25718 0.15225 1.77763 0.39076 0.37923 0.08336 57500.070383 0.000363 0.35248 0.08514 1.00000 1 5.07113 0.63346 1.07621 0.13443 1.78748 0.36956 0.37944 0.07845 57500.071211 0.000465 0.28543 0.07172 0.96875 1 4.43730 0.52667 0.93645 0.11115 1.26652 0.28048 0.26729 0.05919 57500.072083 0.000407 0.24365 0.06143 0.92857 1 5.89312 0.64620 1.24659 0.13668 1.43583 0.32600 0.30331 0.06887 57500.072853 0.000363 0.31156 0.08022 1.00000 1 4.92357 0.62840 1.02859 0.13128 1.53400 0.34302 0.32000 0.07155 57500.073637 0.000421 0.35230 0.08803 1.00000 1 4.11336 0.53602 0.85717 0.11171 1.44914 0.30897 0.30345 0.06470 57500.074479 0.000421 0.22782 0.05748 1.00000 1 5.72241 0.62870 1.20003 0.13182 1.30369 0.29611 0.27193 0.06175 57500.075365 0.000465 0.29050 0.07018 0.98439 1 4.78302 0.55986 0.99433 0.11639 1.38949 0.29363 0.28844 0.06095
