/* ** ** 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 54867.223792 0.000376 0.49158 0.07794 0.97692 0 4.14856 0.38189 2.00280 0.18082 2.03933 0.26327 0.99378 0.12520 54867.224585 0.000417 0.32257 0.05292 0.96528 0 4.66080 0.37602 2.27250 0.18265 1.50341 0.21478 0.71690 0.10198 54867.225317 0.000315 0.39592 0.06668 0.98165 0 4.49470 0.40357 2.37582 0.21326 1.77956 0.25355 0.94036 0.13397 54867.226012 0.000379 0.43324 0.07469 0.97710 0 3.36764 0.31969 1.78553 0.16950 1.45898 0.20996 0.77043 0.11089 54867.226738 0.000347 0.38444 0.06484 0.96667 0 4.33359 0.38666 2.21181 0.19729 1.66599 0.23845 0.85459 0.12228 54867.227453 0.000367 0.42093 0.07155 0.94488 0 3.85152 0.35338 1.96579 0.18034 1.62123 0.23197 0.82610 0.11820 54867.228135 0.000315 0.41130 0.06815 0.96330 0 4.60723 0.41768 2.41093 0.21856 1.89496 0.26280 0.99213 0.13758 54867.228755 0.000304 0.37610 0.06405 0.98095 0 5.04722 0.45187 2.51386 0.22499 1.89824 0.27502 0.95240 0.13790 54867.229478 0.000420 0.34810 0.05758 0.95172 0 4.18316 0.35124 2.07817 0.17442 1.45617 0.20750 0.72912 0.10387 54867.230294 0.000396 0.32636 0.05343 0.95620 0 4.69520 0.38007 2.32939 0.18842 1.53232 0.21808 0.76068 0.10821 54867.231032 0.000341 0.37326 0.06174 0.99153 0 4.64399 0.40849 2.34759 0.20650 1.73340 0.24282 0.87325 0.12228 54867.231680 0.000307 0.51273 0.09062 0.98113 0 3.65451 0.37434 1.86216 0.19064 1.87378 0.26988 0.94822 0.13648 54867.232392 0.000405 0.35766 0.05906 0.97143 0 4.26249 0.36262 2.06087 0.17519 1.52454 0.21576 0.73652 0.10416 54867.233419 0.000622 0.49992 0.06189 0.95677 0 3.96029 0.28539 1.94346 0.13997 1.97983 0.19929 0.97357 0.09800 54867.485396 0.000301 0.33110 0.05436 0.99038 0 3.39147 0.27773 2.92081 0.23918 1.12291 0.15981 0.96712 0.13764 54867.486761 0.001065 0.37032 0.03118 0.98641 0 3.41751 0.14948 2.93580 0.12840 1.26557 0.09106 1.08700 0.07821 54867.488767 0.000940 0.45250 0.03913 0.97846 0 3.21298 0.15517 2.74924 0.13277 1.45389 0.10429 1.24430 0.08925 54867.490723 0.001016 0.37997 0.03171 0.97721 0 3.56609 0.15615 3.05934 0.13395 1.35500 0.09627 1.16329 0.08265 54867.492734 0.000995 0.40779 0.03441 0.98256 0 3.37445 0.15337 2.90012 0.13180 1.37606 0.09783 1.18315 0.08411 54867.494710 0.000981 0.40259 0.03409 0.97050 0 3.50699 0.15910 2.99408 0.13583 1.41186 0.10096 1.20606 0.08623 54867.497129 0.001438 0.42419 0.02920 0.96781 0 3.47411 0.13043 2.96431 0.11128 1.47370 0.08502 1.25738 0.07254
