/* ** ** 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 58245.321365 0.000587 0.37400 0.06235 0.97537 0 1.61763 0.14099 1.35056 0.11770 0.60499 0.08598 0.50370 0.07158 58245.322586 0.000634 0.30902 0.05008 0.97260 0 1.81327 0.14349 1.52413 0.12060 0.56034 0.07925 0.47027 0.06651 58245.323671 0.000451 0.44133 0.07541 0.97436 0 1.78832 0.16968 1.48768 0.14115 0.78924 0.11216 0.65614 0.09324 58245.324704 0.000582 0.32074 0.05285 0.97512 0 1.88595 0.15267 1.57319 0.12735 0.60490 0.08681 0.50441 0.07238 58245.325800 0.000515 0.39663 0.06719 0.97191 0 1.73866 0.15839 1.44892 0.13198 0.68960 0.09850 0.57398 0.08196 58245.326865 0.000550 0.36677 0.06127 0.98421 0 1.73282 0.15219 1.45527 0.12780 0.63554 0.09031 0.53333 0.07579 58245.327730 0.000315 0.22532 0.05654 0.97248 0 1.99770 0.21659 1.65917 0.17987 0.45013 0.10187 0.37389 0.08462 58245.328668 0.000622 0.34989 0.05770 0.97674 0 1.62073 0.13745 1.36390 0.11567 0.56708 0.08020 0.47698 0.06746 58245.329750 0.000460 0.43720 0.07464 0.96855 0 1.77592 0.16987 1.49121 0.14262 0.77642 0.10981 0.65043 0.09199 58245.330659 0.000448 0.48238 0.08392 0.97419 0 1.63172 0.16377 1.36916 0.13742 0.78711 0.11185 0.66048 0.09386 58245.331715 0.000608 0.35019 0.05786 0.97143 0 1.69383 0.14480 1.41834 0.12125 0.59316 0.08386 0.49658 0.07020 58245.332768 0.000446 0.42328 0.07317 0.98701 0 1.82432 0.17586 1.53659 0.14812 0.77220 0.11080 0.65042 0.09333 58245.333700 0.000486 0.43028 0.07406 0.98214 0 1.65326 0.15719 1.39258 0.13241 0.71137 0.10207 0.59918 0.08597 58245.334712 0.000527 0.47130 0.08075 0.96703 0 1.45628 0.14238 1.22651 0.11992 0.68634 0.09656 0.57805 0.08133 58245.335769 0.000524 0.39424 0.06684 0.97790 0 1.68267 0.15193 1.41694 0.12794 0.66338 0.09519 0.55855 0.08015 58245.336848 0.000556 0.39773 0.06764 0.96875 0 1.59544 0.14560 1.33335 0.12167 0.63455 0.09106 0.53153 0.07627 58245.337869 0.000466 0.52795 0.09334 0.95652 0 1.47340 0.15514 1.24054 0.13062 0.77788 0.11048 0.65498 0.09303 58245.338954 0.000619 0.36157 0.05721 0.95327 0 1.81075 0.15022 1.52458 0.12648 0.65471 0.08820 0.55124 0.07426
