/* ** ** 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 58607.250448 0.000512 0.35594 0.05898 0.98870 0 1.90494 0.16446 1.60635 0.13867 0.67806 0.09590 0.57238 0.08095 58607.251272 0.000312 0.54957 0.09841 0.98148 0 1.97810 0.21001 1.69031 0.17945 1.08710 0.15676 0.92902 0.13396 58607.251987 0.000402 0.41727 0.07137 0.99281 0 2.00842 0.18774 1.71953 0.16073 0.83804 0.12005 0.71768 0.10281 58607.252803 0.000414 0.34547 0.05817 0.98601 0 2.34607 0.20022 2.01004 0.17154 0.81048 0.11763 0.69442 0.10078 58607.253674 0.000457 0.37457 0.06254 0.97468 0 2.01637 0.17597 1.72683 0.15070 0.75527 0.10750 0.64678 0.09206 58607.254695 0.000564 0.32353 0.05345 0.98462 0 1.86133 0.15317 1.59410 0.13118 0.60219 0.08627 0.51583 0.07390 58607.255682 0.000422 0.44460 0.07591 0.96575 0 1.86386 0.17827 1.59796 0.15284 0.82868 0.11719 0.71040 0.10047 58607.256675 0.000570 0.31793 0.05183 0.99492 0 1.89398 0.15235 1.62158 0.13044 0.60215 0.08539 0.51553 0.07311 58607.257707 0.000463 0.58542 0.08498 0.96875 0 1.96226 0.17281 1.68114 0.14806 1.14875 0.13256 0.98430 0.11359 58607.258532 0.000362 0.58454 0.10723 0.99200 0 1.58336 0.17763 1.35017 0.15147 0.92554 0.13433 0.78962 0.11460 58607.259397 0.000503 0.34318 0.05689 1.00000 0 1.94879 0.16562 1.66796 0.14176 0.66879 0.09519 0.57243 0.08148 58607.260300 0.000399 0.37387 0.06261 1.00000 0 2.26212 0.19959 1.92728 0.17005 0.84575 0.12039 0.72176 0.10273 58607.261246 0.000547 0.41208 0.06251 0.97354 0 1.94954 0.16200 1.66862 0.13866 0.80337 0.10195 0.68763 0.08726
