/* ** ** 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 55568.054058 0.000790 0.42175 0.03604 0.95971 0 4.19357 0.19282 3.57160 0.16420 1.76865 0.12737 1.50490 0.10836 55568.055629 0.000781 0.43825 0.03754 0.97407 0 4.03117 0.18944 3.45302 0.16226 1.76666 0.12650 1.51084 0.10818 55568.057206 0.000796 0.43368 0.03717 0.97091 0 4.00016 0.18868 3.42462 0.16153 1.73479 0.12416 1.48469 0.10626 55568.058824 0.000822 0.42024 0.03588 0.97183 0 3.97273 0.18363 3.40847 0.15755 1.66952 0.11985 1.43242 0.10283 55568.060456 0.000810 0.40201 0.03404 0.97143 0 4.23047 0.19185 3.63869 0.16501 1.70070 0.12159 1.46281 0.10458 55568.062039 0.000773 0.45937 0.03957 0.97753 0 3.85993 0.18682 3.31972 0.16067 1.77314 0.12633 1.52493 0.10865 55568.063517 0.000700 0.45979 0.03965 0.97521 0 4.24953 0.20450 3.65306 0.17579 1.95389 0.13984 1.67971 0.12022 55568.065036 0.000819 0.40485 0.03417 0.98233 0 4.13186 0.18904 3.54992 0.16241 1.67277 0.11864 1.43742 0.10195 55568.067322 0.001467 0.41273 0.02609 0.96941 0 4.09288 0.13883 3.51823 0.11934 1.68926 0.09008 1.45223 0.07744 55568.124692 0.000703 0.44277 0.03843 0.98354 0 4.15064 0.19886 3.71277 0.17787 1.83776 0.13302 1.64560 0.11911 55568.126031 0.000637 0.49374 0.04324 0.98636 0 4.10437 0.20665 3.70014 0.18630 2.02649 0.14522 1.82699 0.13092 55568.127442 0.000774 0.41827 0.03591 0.97010 0 4.08680 0.18808 3.61975 0.16658 1.70937 0.12387 1.51312 0.10965 55568.128963 0.000747 0.42725 0.03638 0.98062 0 4.14299 0.19516 3.68710 0.17369 1.77009 0.12557 1.57951 0.11202 55568.130424 0.000715 0.47474 0.04152 0.99595 0 3.85084 0.19141 3.40453 0.16920 1.82816 0.13155 1.61495 0.11622 55568.131888 0.000749 0.42230 0.03612 0.99614 0 4.08564 0.19166 3.65153 0.17129 1.72538 0.12339 1.53867 0.11002 55568.134032 0.001395 0.40746 0.02624 0.98548 0 4.04223 0.14071 3.56663 0.12414 1.64706 0.08926 1.45244 0.07870
