/* ** ** 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 58197.427688 0.000443 0.39942 0.06765 0.98693 0 1.93525 0.17783 1.65236 0.15182 0.77299 0.10998 0.65987 0.09388 58197.428548 0.000417 0.51953 0.09163 0.98611 0 1.56285 0.16289 1.35023 0.14073 0.81195 0.11552 0.70169 0.09983 58197.429398 0.000434 0.43221 0.07300 0.99333 0 1.84492 0.17126 1.59298 0.14788 0.79740 0.11251 0.68854 0.09715 58197.430232 0.000399 0.41825 0.07159 0.99275 0 2.01966 0.19224 1.73895 0.16549 0.84472 0.12017 0.72730 0.10347 58197.431109 0.000477 0.32915 0.05515 0.98788 0 2.12174 0.17871 1.82496 0.15371 0.69837 0.10116 0.60159 0.08715 58197.432046 0.000460 0.38533 0.06509 0.98742 0 1.91370 0.17428 1.64653 0.14996 0.73740 0.10492 0.63465 0.09029 58197.432871 0.000365 0.47091 0.08162 0.99206 0 1.98948 0.19865 1.71778 0.17152 0.93687 0.13274 0.80893 0.11461 58197.433721 0.000486 0.36854 0.06184 0.97619 0 1.92015 0.17087 1.64472 0.14635 0.70764 0.10068 0.60756 0.08644 58197.434546 0.000339 0.55284 0.09903 0.99145 0 1.79779 0.19362 1.54613 0.16651 0.99388 0.14226 0.85442 0.12229 58197.435342 0.000457 0.44370 0.07624 0.96835 0 1.69969 0.16376 1.46777 0.14142 0.75414 0.10729 0.65124 0.09265 58197.436201 0.000402 0.50939 0.08879 0.94964 0 1.72780 0.17606 1.48963 0.15179 0.88012 0.12447 0.75884 0.10732 58197.437133 0.000530 0.31215 0.05097 0.98361 0 2.07545 0.16942 1.78042 0.14533 0.64785 0.09162 0.55648 0.07870 58197.438154 0.000492 0.46612 0.07368 0.97647 0 1.81389 0.16377 1.54407 0.13939 0.84549 0.10970 0.72092 0.09353
