/* ** ** 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 58198.358016 0.000391 0.42807 0.11352 0.90370 0 1.93361 0.27973 0.82536 0.11685 0.82772 0.18396 0.34484 0.07525 58198.358996 0.000590 0.41482 0.11154 0.95098 0 1.48918 0.22196 0.50198 0.07474 0.61774 0.13824 0.20653 0.04618 58198.360096 0.000492 0.43810 0.11866 0.97647 0 1.70917 0.26106 0.54763 0.08363 0.74879 0.16749 0.24137 0.05397 58198.361005 0.000417 0.86818 0.27739 0.97222 0 0.97059 0.21367 0.31929 0.07023 0.84265 0.19512 0.27699 0.06410 58198.361936 0.000515 0.39099 0.10348 0.92697 0 1.97255 0.27883 0.61775 0.08728 0.77125 0.17256 0.24283 0.05430 58198.363010 0.000558 0.30836 0.07970 0.95855 0 2.20680 0.28582 0.69893 0.09049 0.68050 0.15220 0.21658 0.04843 58198.364433 0.000865 0.34953 0.07311 0.98263 0 1.98413 0.21963 0.62382 0.06904 0.69351 0.12307 0.21746 0.03858 58198.424139 0.000428 0.38615 0.06489 0.98649 0 2.14804 0.19332 1.80763 0.16269 0.82946 0.11772 0.69907 0.09921 58198.425036 0.000469 0.32560 0.05360 0.97531 0 2.33077 0.19308 1.93350 0.16018 0.75890 0.10797 0.63063 0.08972 58198.426000 0.000495 0.49185 0.08697 0.96491 0 1.46452 0.15206 1.22027 0.12672 0.72032 0.10310 0.60068 0.08597 58198.426984 0.000489 0.37778 0.06376 0.97633 0 1.92446 0.17478 1.59827 0.14514 0.72701 0.10343 0.60388 0.08591 58198.428309 0.000836 0.42255 0.05406 0.96886 0 1.81785 0.12895 1.50856 0.10700 0.76814 0.08179 0.63828 0.06795
