/* ** ** 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 55209.040678 0.000692 0.47024 0.04072 0.98326 0 4.17698 0.20500 3.59634 0.17650 1.96420 0.14014 1.69157 0.12068 55209.042035 0.000666 0.52060 0.04587 0.97826 0 3.93995 0.20336 3.41012 0.17602 2.05113 0.14646 1.77523 0.12676 55209.043409 0.000709 0.48500 0.04213 0.98367 0 3.92807 0.19471 3.40111 0.16859 1.90513 0.13592 1.64945 0.11768 55209.044798 0.000680 0.48862 0.04256 0.98298 0 4.06072 0.20232 3.51678 0.17522 1.98414 0.14177 1.71859 0.12279 55209.046227 0.000749 0.42547 0.03623 0.97683 0 4.29581 0.20150 3.71684 0.17434 1.82774 0.12988 1.58121 0.11236 55209.047801 0.000825 0.45862 0.03723 0.96608 0 4.05982 0.18312 3.51320 0.15847 1.86190 0.12568 1.61113 0.10875 55209.244841 0.000689 0.48317 0.04199 0.98739 0 4.06797 0.20247 3.49946 0.17417 1.96553 0.14002 1.69381 0.12066 55209.246219 0.000689 0.50128 0.04410 0.97899 0 3.90968 0.19827 3.38191 0.17150 1.95985 0.14087 1.69484 0.12182 55209.248114 0.001207 0.45958 0.03116 0.97700 0 3.99281 0.15267 3.43259 0.13124 1.83503 0.10274 1.57692 0.08828 55209.311582 0.000758 0.41937 0.03566 0.98092 0 4.30137 0.19906 3.68334 0.17046 1.80386 0.12870 1.54669 0.11035 55209.313064 0.000723 0.39737 0.03345 0.97600 0 4.83744 0.21662 4.11249 0.18415 1.92226 0.13702 1.63515 0.11654 55209.314522 0.000735 0.47531 0.04110 0.98031 0 3.99112 0.19552 3.36266 0.16473 1.89700 0.13516 1.59851 0.11388 55209.316652 0.001395 0.47757 0.02986 0.97303 0 3.99659 0.14130 3.40960 0.12054 1.90865 0.09842 1.62765 0.08393
