/* ** ** 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 58163.423583 0.000425 0.57150 0.10232 0.96599 0 1.50214 0.16156 1.22149 0.13138 0.85848 0.12287 0.69792 0.09990 58163.424453 0.000446 0.48562 0.08565 0.96753 0 1.65695 0.16875 1.35965 0.13845 0.80465 0.11587 0.66157 0.09527 58163.425446 0.000547 0.37091 0.06180 0.98942 0 1.77765 0.15579 1.46027 0.12797 0.65934 0.09344 0.54069 0.07661 58163.426308 0.000315 0.26127 0.06508 0.98165 0 1.81215 0.20704 1.48705 0.16988 0.47347 0.10481 0.38822 0.08594 58163.427275 0.000651 0.37532 0.06237 0.96000 0 1.49650 0.13062 1.23598 0.10788 0.56166 0.07943 0.46374 0.06558 58163.428464 0.000538 0.41541 0.07036 0.96237 0 1.63225 0.15000 1.34012 0.12314 0.67805 0.09647 0.55663 0.07919 58163.429494 0.000492 0.44258 0.07606 0.97647 0 1.66140 0.15949 1.36918 0.13144 0.73530 0.10481 0.60589 0.08636 58163.430319 0.000333 0.30155 0.07525 0.96522 0 1.55353 0.18540 1.28512 0.15337 0.46846 0.10267 0.38749 0.08492 58163.431094 0.000443 0.58659 0.10597 0.97386 0 1.37964 0.15357 1.13952 0.12685 0.80928 0.11514 0.66870 0.09514 58163.432046 0.000509 0.35611 0.06014 0.98864 0 1.91381 0.16607 1.58216 0.13729 0.68153 0.09875 0.56347 0.08164 58163.433637 0.001082 0.43711 0.05433 0.97059 0 1.44963 0.10029 1.19363 0.08258 0.63365 0.06543 0.52136 0.05383
