/* ** ** 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 58209.011801 0.000356 0.16036 0.03855 0.95122 0 2.51381 0.22168 2.13362 0.18815 0.40312 0.09014 0.34245 0.07657 58209.012588 0.000431 0.14083 0.03423 0.99329 0 2.23727 0.19431 1.90294 0.16526 0.31507 0.07152 0.26712 0.06064 58209.013462 0.000443 0.18486 0.04137 0.97943 0 2.14326 0.18917 1.80347 0.15915 0.39621 0.08149 0.33334 0.06854 58210.995901 0.000469 0.13109 0.03172 0.96914 0 2.38720 0.19961 1.91965 0.16049 0.31294 0.07106 0.25187 0.05716 58210.996833 0.000463 0.15014 0.03711 0.95625 0 2.07166 0.18538 1.69843 0.15197 0.31104 0.07166 0.25503 0.05876 58210.997724 0.000428 0.15141 0.03811 0.97973 0 2.13903 0.19868 1.75358 0.16288 0.32387 0.07576 0.26549 0.06210 58210.999073 0.000920 0.14028 0.02488 0.96487 0 2.08672 0.13164 1.70994 0.10786 0.29274 0.04851 0.23987 0.03975
