/* ** ** 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 56775.337799 0.000718 0.31449 0.02562 0.97984 0 5.82262 0.23140 5.25214 0.20872 1.83116 0.13022 1.65159 0.11744 56775.339300 0.000784 0.25716 0.02107 0.98524 0 6.27597 0.22994 5.67409 0.20788 1.61395 0.11830 1.45896 0.10693 56775.340843 0.000758 0.28722 0.02316 0.98092 0 6.00692 0.23004 5.41501 0.20736 1.72529 0.12243 1.55469 0.11032 56775.342370 0.000770 0.27373 0.02217 0.98496 0 6.12749 0.22959 5.53766 0.20748 1.67726 0.12042 1.51568 0.10882 56775.343939 0.000799 0.27452 0.02217 0.98188 0 5.91541 0.22164 5.35375 0.20059 1.62389 0.11617 1.46945 0.10513 56775.345524 0.000787 0.25903 0.02080 0.99265 0 6.30463 0.22994 5.69099 0.20756 1.63312 0.11686 1.47489 0.10552 56775.347015 0.000703 0.31363 0.02555 0.98354 0 5.89672 0.23536 5.34227 0.21323 1.84939 0.13137 1.67550 0.11902 56775.348849 0.001131 0.28180 0.01893 0.97954 0 5.93577 0.18664 5.35031 0.16822 1.67272 0.09928 1.50759 0.08946
