/* ** ** 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 56401.327092 0.000356 0.37038 0.06133 0.96748 0 2.69160 0.23184 2.27019 0.19551 0.99692 0.14099 0.84174 0.11904 56401.327767 0.000318 0.39858 0.06727 0.97273 0 2.77270 0.25222 2.33891 0.21274 1.10515 0.15712 0.93173 0.13246 56401.328438 0.000353 0.45315 0.07722 0.98361 0 2.19864 0.21116 1.87139 0.17972 0.99631 0.14025 0.84749 0.11929 56401.329161 0.000370 0.34907 0.05825 0.95312 0 2.72186 0.23101 2.31726 0.19667 0.95012 0.13651 0.80945 0.11631 56401.329844 0.000312 0.41827 0.07107 0.93519 0 2.80243 0.25752 2.34300 0.21530 1.17217 0.16753 0.98242 0.14041 56401.330469 0.000312 0.37311 0.06254 0.97222 0 3.00502 0.26325 2.53532 0.22209 1.12120 0.16024 0.94499 0.13506 56401.331948 0.001166 0.45746 0.03943 0.92060 0 2.77982 0.13310 2.33287 0.11168 1.27166 0.09113 1.06726 0.07647 56401.333449 0.000336 0.37692 0.06482 0.91379 0 2.87032 0.25705 2.42115 0.21676 1.08189 0.15884 0.91384 0.13416 56401.335023 0.001238 0.37737 0.03325 0.90888 0 3.04086 0.14050 2.55125 0.11787 1.14753 0.08611 0.96032 0.07206 56401.336838 0.000576 0.38455 0.04848 0.90955 0 3.01005 0.20089 2.55925 0.17080 1.15751 0.12382 0.98311 0.10516 56401.337801 0.000388 0.33254 0.05399 0.94776 0 2.89325 0.23724 2.44737 0.20067 0.96214 0.13481 0.81284 0.11387
