/* ** ** 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 58230.062112 0.000524 0.14996 0.03604 0.97238 0 1.90188 0.16745 1.51944 0.13378 0.28520 0.06378 0.22765 0.05090 58230.063206 0.000570 0.17077 0.04145 0.97462 0 1.56775 0.14804 1.22487 0.11567 0.26772 0.05987 0.20868 0.04666 58230.064462 0.000686 0.12363 0.02942 0.97468 0 1.79792 0.14635 1.40698 0.11452 0.22228 0.04970 0.17345 0.03878 58230.065807 0.000660 0.13582 0.03244 0.98246 0 1.68678 0.14146 1.31693 0.11044 0.22910 0.05123 0.17887 0.04000 58230.067069 0.000602 0.11167 0.02637 0.97596 0 2.26209 0.17150 1.76954 0.13413 0.25260 0.05649 0.19737 0.04413 58230.068362 0.000692 0.10324 0.02431 0.96234 0 2.15938 0.15899 1.68432 0.12401 0.22294 0.04985 0.17420 0.03895 58230.069731 0.000677 0.13469 0.03261 0.97863 0 1.63340 0.13776 1.28250 0.10815 0.22001 0.04993 0.17273 0.03919 58230.070868 0.000460 0.19411 0.04838 1.00000 0 1.60839 0.16602 1.27452 0.13153 0.31221 0.07084 0.24877 0.05644 58230.072121 0.000793 0.12146 0.02686 0.98175 0 1.78049 0.13117 1.41172 0.10399 0.21626 0.04510 0.17129 0.03572
