/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 58496.494304 0.000362 0.41381 0.06983 0.96800 0 2.37967 0.21902 2.00122 0.18419 0.98474 0.13929 0.82782 0.11707 58496.495022 0.000356 0.36429 0.06190 0.98374 0 2.66215 0.23647 2.22000 0.19718 0.96979 0.14047 0.81056 0.11739 58496.495704 0.000327 0.42216 0.07232 0.98230 0 2.53762 0.23881 2.11683 0.19921 1.07129 0.15334 0.89299 0.12779 58496.496480 0.000448 0.30055 0.04859 0.97419 0 2.63438 0.20641 2.20601 0.17284 0.79176 0.11198 0.66336 0.09381 58496.497310 0.000382 0.37605 0.06404 0.96212 0 2.43805 0.21840 2.05353 0.18396 0.91682 0.13278 0.77226 0.11184 58496.498048 0.000356 0.35432 0.06016 0.97561 0 2.72947 0.23793 2.29419 0.19998 0.96712 0.14091 0.81296 0.11845 58496.498884 0.000480 0.29811 0.04842 0.96988 0 2.50911 0.19557 2.09208 0.16307 0.74800 0.10659 0.62486 0.08904 58496.499755 0.000391 0.40376 0.06768 0.97778 0 2.27830 0.20704 1.90544 0.17317 0.91990 0.12957 0.77006 0.10846 58496.500542 0.000396 0.32348 0.05257 0.94891 0 2.83067 0.22670 2.38254 0.19081 0.91567 0.12950 0.77051 0.10897 58496.501393 0.000454 0.33670 0.05569 0.97452 0 2.30564 0.19108 1.92749 0.15974 0.77632 0.11112 0.64786 0.09271 58496.502235 0.000388 0.38879 0.06556 0.97761 0 2.34264 0.21211 1.95475 0.17694 0.91080 0.12957 0.76064 0.10821 58496.503014 0.000391 0.34984 0.05839 0.97778 0 2.57732 0.22142 2.15101 0.18479 0.90165 0.12903 0.75093 0.10746 58496.503783 0.000379 0.31561 0.05178 0.98473 0 2.90505 0.23739 2.44653 0.19992 0.91688 0.13043 0.77244 0.10989 58496.504834 0.000671 0.38070 0.04872 0.96552 0 2.40604 0.16292 2.00844 0.13599 0.91597 0.09946 0.76447 0.08300
