/* ** ** 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 56830.002760 0.000436 0.40232 0.06974 0.99892 1 7.23518 0.68259 1.58374 0.14941 2.91083 0.42332 0.63617 0.09252 56830.004118 0.000408 0.35770 0.03000 0.97163 0 8.97603 0.38099 8.04514 0.34145 3.21076 0.23227 2.87911 0.20828 56830.004894 0.000367 0.40072 0.03401 0.99213 0 8.83870 0.40103 7.83809 0.35563 3.54181 0.25401 3.14360 0.22544 56830.005663 0.000402 0.37534 0.03133 0.98561 0 8.76491 0.38267 7.77905 0.33958 3.28979 0.23401 2.91917 0.20764 56830.006474 0.000408 0.34947 0.02915 0.99291 0 9.07463 0.38671 8.08425 0.34450 3.17128 0.22742 2.82924 0.20289 56830.007272 0.000391 0.37902 0.03195 1.00000 0 8.73860 0.38711 7.74520 0.34311 3.31207 0.23753 2.93403 0.21041 56830.008080 0.000411 0.35661 0.02958 0.97183 0 9.20386 0.38663 8.09767 0.34014 3.28221 0.23480 2.88476 0.20635 56830.008875 0.000385 0.37709 0.03182 1.00000 0 8.82610 0.38934 7.89027 0.34803 3.32825 0.23946 2.97946 0.21432 56830.009668 0.000408 0.33221 0.02758 1.00000 0 9.48245 0.39337 8.44289 0.35021 3.15014 0.22657 2.80269 0.20156 56830.010513 0.000437 0.31718 0.02622 0.98675 0 9.41880 0.38043 8.33706 0.33669 2.98742 0.21549 2.64607 0.19084 56830.011370 0.000420 0.36027 0.02875 0.99956 0 9.32478 0.38565 8.29321 0.34295 3.35940 0.22925 2.98678 0.20381
