/* ** ** 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 58194.306829 0.000405 0.38351 0.06492 0.96429 0 2.33938 0.20855 1.89584 0.16897 0.89717 0.12911 0.73061 0.10514 58194.307581 0.000347 0.56823 0.10213 0.95000 0 1.91381 0.20823 1.52812 0.16627 1.08749 0.15558 0.86968 0.12442 58194.308327 0.000399 0.38827 0.06557 0.97826 0 2.42858 0.21799 1.89373 0.16997 0.94293 0.13488 0.73440 0.10507 58194.309042 0.000315 0.57381 0.10197 0.95413 0 2.13496 0.22740 1.66432 0.17727 1.22507 0.17427 0.95822 0.13630 58194.309737 0.000379 0.50325 0.09000 0.93893 0 1.99232 0.20443 1.57057 0.16112 1.00263 0.14685 0.78942 0.11562 58194.310544 0.000428 0.49134 0.08576 0.98649 0 1.75202 0.17723 1.38663 0.14028 0.86084 0.12246 0.68257 0.09709 58194.311334 0.000362 0.36556 0.06223 0.96800 0 2.81952 0.24870 2.20484 0.19448 1.03071 0.15007 0.80669 0.11745 58194.312074 0.000379 0.42318 0.07257 0.98473 0 2.32360 0.22255 1.82620 0.17491 0.98329 0.13988 0.77252 0.10988 58194.312795 0.000341 0.48542 0.08403 0.98305 0 2.31111 0.23197 1.82548 0.18321 1.12186 0.15822 0.88482 0.12477 58194.313596 0.000460 0.36663 0.06139 0.98742 0 2.19876 0.19326 1.75070 0.15388 0.80613 0.11488 0.64099 0.09130 58194.314476 0.000420 0.38639 0.06559 0.95862 0 2.33570 0.21346 1.84175 0.16829 0.90250 0.12910 0.71327 0.10204 58194.315269 0.000373 0.48539 0.08470 0.95349 0 2.10210 0.20743 1.65321 0.16312 1.02033 0.14685 0.80189 0.11539 58194.316007 0.000365 0.38763 0.06528 0.96825 0 2.69409 0.24292 2.10793 0.19006 1.04431 0.14855 0.81685 0.11619 58194.316710 0.000339 0.50703 0.08924 0.98291 0 2.18597 0.22410 1.69973 0.17425 1.10836 0.15857 0.86212 0.12334 58194.317436 0.000388 0.45590 0.07359 0.98507 0 2.44117 0.22221 1.90910 0.17376 1.11292 0.14835 0.86863 0.11578
