/* ** ** 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 59649.256464 0.000628 0.26470 0.02154 0.98618 0 7.92853 0.29472 6.94564 0.25816 2.09869 0.15189 1.83814 0.13302 59649.257717 0.000625 0.26308 0.02137 0.99074 0 8.03178 0.29931 7.01908 0.26153 2.11304 0.15253 1.84750 0.13335 59649.258918 0.000576 0.28171 0.02356 0.98492 0 7.92914 0.30722 7.00931 0.27158 2.23370 0.16558 1.97457 0.14637 59649.260035 0.000541 0.30428 0.02468 0.98930 0 8.03388 0.31572 7.09984 0.27901 2.44455 0.17342 2.16013 0.15325 59649.261100 0.000524 0.31183 0.02570 0.98343 0 8.11651 0.32699 7.12845 0.28716 2.53098 0.18197 2.22162 0.15970 59649.262231 0.000608 0.25873 0.02091 0.97143 0 8.45296 0.30824 7.47254 0.27249 2.18704 0.15774 1.93336 0.13944 59649.263368 0.000530 0.29466 0.02400 0.97268 0 8.55092 0.33152 7.55975 0.29310 2.51959 0.18053 2.22749 0.15960 59649.264413 0.000515 0.33895 0.02809 0.96629 0 7.71150 0.32059 6.81751 0.28342 2.61380 0.18741 2.31077 0.16569 59649.265504 0.000576 0.28598 0.02327 0.96985 0 8.10413 0.30907 7.16461 0.27324 2.31764 0.16661 2.04896 0.14729 59649.266609 0.000530 0.33144 0.02732 0.99454 0 7.49351 0.31169 6.60212 0.27460 2.48363 0.17678 2.19000 0.15588 59649.267934 0.000790 0.29549 0.02015 0.98901 0 8.07725 0.26378 7.14025 0.23318 2.38671 0.14291 2.10983 0.12633
