/* ** ** 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 59635.638794 0.000940 0.31186 0.02563 0.96000 0 6.06712 0.24327 4.04878 0.16178 1.89212 0.13577 1.27078 0.09093 59635.640079 0.000344 0.25524 0.03823 0.94958 0 5.97016 0.40413 3.89021 0.26333 1.52383 0.20363 0.99280 0.13267 59635.641561 0.001137 0.27120 0.02195 0.95929 0 5.96058 0.22198 3.85616 0.14356 1.61649 0.11619 1.04752 0.07529 59635.643112 0.000414 0.27295 0.03729 0.95804 0 5.59610 0.35217 3.64410 0.22933 1.52743 0.18523 0.99436 0.12058 59635.644555 0.001030 0.28230 0.02275 0.97753 0 6.27370 0.23725 4.06081 0.15356 1.77105 0.12604 1.14808 0.08170 59635.645898 0.000312 0.24231 0.03811 0.96296 0 6.20953 0.43432 4.01834 0.28106 1.50464 0.21194 0.97738 0.13766 59635.646514 0.000304 0.23921 0.03793 0.96190 0 6.42732 0.45005 4.12075 0.28847 1.53748 0.21874 0.98657 0.14035 59635.647724 0.000906 0.25700 0.02447 0.95744 0 5.74975 0.24704 3.62741 0.15579 1.47770 0.12557 0.93560 0.07946 59635.782647 0.000642 0.27399 0.02249 0.98198 0 8.04600 0.30445 6.55070 0.24786 2.20451 0.16057 1.79516 0.13074 59635.784045 0.000755 0.24868 0.01997 0.98467 0 7.47323 0.26973 6.23328 0.22498 1.85844 0.13332 1.55042 0.11123 59635.785451 0.000651 0.29141 0.02365 0.94667 0 7.80314 0.29689 6.40533 0.24368 2.27393 0.16301 1.86616 0.13379 59635.786837 0.000735 0.24186 0.01961 0.98425 0 7.85104 0.27976 6.46499 0.23032 1.89883 0.13831 1.56538 0.11401 59635.788573 0.001001 0.25470 0.01688 0.97688 0 8.14138 0.24255 6.73981 0.20078 2.07362 0.12278 1.71823 0.10173
