/* ** ** 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 56764.004896 0.000312 0.44458 0.07540 0.97222 0 2.48478 0.23236 2.16829 0.20276 1.10467 0.15631 0.96397 0.13641 56764.005529 0.000321 0.36219 0.05883 0.97297 0 3.08268 0.26025 2.69004 0.22710 1.11650 0.15492 0.97429 0.13519 56764.006186 0.000336 0.39352 0.06272 0.97414 0 2.86657 0.24333 2.50146 0.21234 1.12805 0.15219 0.98437 0.13280 56764.007089 0.000567 0.36298 0.04432 0.96429 0 3.10578 0.19553 2.71020 0.17063 1.12735 0.11794 0.98376 0.10292 56764.007963 0.000307 0.44835 0.07745 0.98113 0 2.43832 0.23648 2.12776 0.20636 1.09322 0.15627 0.95398 0.13636 56764.008651 0.000382 0.39132 0.05901 0.96212 0 2.86628 0.22778 2.50120 0.19876 1.12163 0.14374 0.97877 0.12543 56764.009369 0.000336 0.35883 0.05909 0.97414 0 2.86058 0.24101 2.49623 0.21031 1.02646 0.14525 0.89573 0.12675 56764.010767 0.001062 0.37134 0.03283 0.96752 0 3.07431 0.14068 2.68274 0.12277 1.14162 0.08634 0.99621 0.07534 56764.185105 0.000373 0.35631 0.05880 0.98450 0 3.92196 0.33356 2.21357 0.18826 1.39743 0.19763 0.78871 0.11154 56764.185843 0.000365 0.47442 0.08196 0.96825 0 3.05037 0.29897 1.72164 0.16874 1.44716 0.20586 0.81679 0.11619 56764.186526 0.000318 0.47102 0.08223 1.00000 0 3.38980 0.33906 1.91322 0.19137 1.59668 0.22847 0.90117 0.12895 56764.187197 0.000353 0.38347 0.06497 0.98361 0 3.79681 0.33926 2.14294 0.19148 1.45596 0.20957 0.82175 0.11828 56764.187967 0.000417 0.40709 0.06881 0.97917 0 3.07587 0.28085 1.73604 0.15851 1.25215 0.17812 0.70672 0.10053 56764.188791 0.000408 0.45469 0.07770 0.95035 0 2.91278 0.27941 1.64399 0.15770 1.32443 0.18730 0.74751 0.10571 56764.189665 0.000466 0.36175 0.05992 0.96894 0 3.14487 0.27115 1.77498 0.15304 1.13765 0.16089 0.64209 0.09081 56764.190556 0.000425 0.36027 0.06010 0.96599 0 3.45117 0.30078 1.94786 0.16976 1.24334 0.17687 0.70175 0.09983 56764.191341 0.000359 0.44569 0.07602 0.98387 0 3.26396 0.31128 1.84220 0.17569 1.45470 0.20573 0.82104 0.11611 56764.192125 0.000425 0.35542 0.05890 0.97279 0 3.47374 0.29531 1.96059 0.16668 1.23464 0.17563 0.69684 0.09913 56764.192970 0.000420 0.38372 0.06494 0.98621 0 3.20084 0.28918 1.80657 0.16321 1.22821 0.17575 0.69321 0.09919 56764.193835 0.000446 0.34776 0.05785 0.98701 0 3.34007 0.28798 1.88515 0.16254 1.16154 0.16523 0.65558 0.09326 56764.194685 0.000405 0.37503 0.06296 0.96429 0 3.46904 0.30464 1.95794 0.17194 1.30100 0.18616 0.73429 0.10507 56764.195394 0.000304 0.47000 0.08231 0.99048 0 3.60938 0.35897 2.03715 0.20260 1.69640 0.24453 0.95746 0.13802 56764.196112 0.000414 0.46409 0.07415 0.98601 0 3.18628 0.29215 1.79835 0.16489 1.47872 0.19347 0.83459 0.10920
