/* ** ** 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 55646.531068 0.000396 0.32679 0.05330 0.97810 0 3.13332 0.25400 2.28924 0.18555 1.02393 0.14490 0.74751 0.10571 55646.531840 0.000376 0.32882 0.05487 0.98462 0 3.05374 0.25315 2.32585 0.19281 1.00413 0.14541 0.76633 0.11097 55646.532593 0.000376 0.40406 0.06827 0.95385 0 2.61272 0.23479 1.97920 0.17786 1.05569 0.15105 0.79943 0.11439 55646.533278 0.000310 0.45041 0.07787 0.98131 0 2.82443 0.27644 2.12091 0.20759 1.27215 0.18131 0.95822 0.13652 55646.533964 0.000376 0.36182 0.06062 0.95385 0 2.88861 0.24775 2.19710 0.18844 1.04514 0.15044 0.79524 0.11447 55646.534656 0.000315 0.46774 0.08166 0.98165 0 2.62285 0.25906 1.97396 0.19495 1.22681 0.17662 0.92159 0.13266 55646.535292 0.000321 0.35583 0.05894 0.98198 0 3.36958 0.28587 2.57131 0.21814 1.19899 0.17056 0.91420 0.13005 55646.535958 0.000344 0.39112 0.06643 0.99160 0 2.84561 0.25649 2.13526 0.19246 1.11298 0.16021 0.83568 0.12029 55646.536658 0.000356 0.35695 0.05960 0.98374 0 3.07554 0.26776 2.33757 0.20350 1.09782 0.15640 0.83151 0.11847 55646.537512 0.000498 0.30259 0.04923 0.97093 0 2.62572 0.20728 1.97232 0.15568 0.79452 0.11302 0.59669 0.08488 55646.538313 0.000304 0.52910 0.09353 0.96190 0 2.44951 0.25423 1.85421 0.19244 1.29603 0.18544 0.98147 0.14044 55646.539048 0.000431 0.28475 0.04551 0.97315 0 3.24814 0.24530 2.45827 0.18564 0.92490 0.13028 0.70104 0.09873 55646.539876 0.000396 0.34099 0.05549 0.97080 0 2.98717 0.24762 2.25483 0.18692 1.01860 0.14264 0.76820 0.10757 55646.540605 0.000333 0.42716 0.07317 0.96522 0 2.76895 0.26068 2.08759 0.19655 1.18278 0.16925 0.89305 0.12779 55646.541647 0.000709 0.40666 0.04910 0.97143 0 2.67179 0.17418 2.01970 0.13165 1.08650 0.11043 0.82054 0.08338
