/* ** ** 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 59710.138917 0.000625 0.32596 0.02711 0.96759 0 7.69833 0.31521 5.79377 0.23719 2.50933 0.18170 1.88208 0.13620 59710.140315 0.000773 0.24342 0.01959 0.98876 0 7.72716 0.27585 6.14140 0.21924 1.88091 0.13567 1.49394 0.10775 59710.141802 0.000715 0.26859 0.02179 0.99190 0 7.59983 0.28567 6.00936 0.22583 2.04127 0.14676 1.61406 0.11603 59710.143217 0.000700 0.25355 0.02051 1.00000 0 8.13393 0.29738 6.42975 0.23507 2.06240 0.14878 1.62975 0.11755 59710.144603 0.000686 0.26354 0.02163 0.97468 0 8.10113 0.29889 6.38181 0.23546 2.13499 0.15656 1.68475 0.12356 59710.145968 0.000680 0.26767 0.02155 0.99149 0 8.10494 0.30030 6.38500 0.23655 2.16946 0.15508 1.71027 0.12223 59710.147349 0.000700 0.24789 0.02003 0.98347 0 8.38044 0.30100 6.66753 0.23945 2.07743 0.15033 1.65275 0.11960 59710.149010 0.000961 0.28214 0.01939 0.98795 0 7.62830 0.24494 6.03039 0.19361 2.15224 0.13074 1.70275 0.10342
