/* ** ** 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 56869.918656 0.000347 0.36897 0.03102 0.99167 0 9.96872 0.43364 9.04531 0.39346 3.67812 0.26457 3.33842 0.24011 56869.919289 0.000286 0.44485 0.03830 0.97980 0 10.12441 0.48207 9.25445 0.44065 4.50385 0.32312 4.11625 0.29529 56869.919903 0.000327 0.39251 0.03338 0.99115 0 9.83029 0.44611 9.03687 0.41011 3.85852 0.27751 3.54708 0.25511 56869.920594 0.000365 0.34124 0.02891 0.99206 0 9.94117 0.41814 9.14011 0.38445 3.39236 0.24948 3.11897 0.22938 56869.921326 0.000367 0.33705 0.02789 0.99213 0 10.22233 0.42651 9.39689 0.39207 3.44548 0.24620 3.16724 0.22632 56869.922018 0.000324 0.41858 0.03559 0.98214 0 9.56228 0.44573 8.74479 0.40762 4.00253 0.28459 3.66435 0.26051 56869.922680 0.000339 0.34714 0.02918 0.99145 0 10.74476 0.45918 9.82538 0.41992 3.72989 0.26998 3.40925 0.24680 56869.923378 0.000359 0.35822 0.02986 0.97581 0 10.02846 0.42735 9.15307 0.39005 3.59235 0.25735 3.28156 0.23509 56869.924069 0.000333 0.36161 0.03044 0.98261 0 10.61709 0.45946 9.73154 0.42113 3.83920 0.27719 3.51749 0.25398 56869.924735 0.000333 0.38814 0.03276 0.99130 0 9.82233 0.44145 9.01712 0.40528 3.81246 0.27242 3.50063 0.25014 56869.925383 0.000315 0.39954 0.03344 0.99083 0 10.37857 0.47022 9.36968 0.42456 4.14661 0.29177 3.74698 0.26364 56869.926005 0.000307 0.42280 0.03682 1.00000 0 9.53840 0.45158 8.73288 0.41348 4.03286 0.29473 3.69501 0.26996 56869.926601 0.000289 0.41170 0.03481 0.99000 0 10.75743 0.49252 9.88945 0.45278 4.42885 0.31486 4.07150 0.28946 56869.927186 0.000295 0.45439 0.03988 1.00000 0 9.28557 0.45765 8.48975 0.41845 4.21924 0.30639 3.85755 0.27999 56869.927782 0.000301 0.40191 0.03500 1.00000 0 10.14714 0.47309 9.32762 0.43488 4.07821 0.29992 3.74876 0.27569 56869.928412 0.000330 0.37390 0.03132 1.00000 0 10.24191 0.45216 9.35924 0.41322 3.82949 0.27255 3.49884 0.24902 56869.929278 0.000535 0.33606 0.02353 0.99459 0 10.03786 0.34913 9.20141 0.32001 3.37330 0.20502 3.09009 0.18778
