/* ** ** 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 58576.318429 0.000339 0.45431 0.07782 0.98291 0 2.26352 0.21874 1.91919 0.18548 1.02833 0.14544 0.87102 0.12318 58576.319135 0.000367 0.42877 0.07353 0.97638 0 2.19928 0.20871 1.86524 0.17701 0.94298 0.13469 0.80057 0.11435 58576.319951 0.000448 0.28967 0.04677 0.98710 0 2.63836 0.20204 2.25058 0.17234 0.76426 0.10862 0.65176 0.09263 58576.320801 0.000402 0.38158 0.06369 0.94245 0 2.34100 0.20489 1.99483 0.17459 0.89327 0.12696 0.76121 0.10819 58576.321719 0.000515 0.29535 0.04922 0.97191 0 2.22848 0.17694 1.89900 0.15078 0.65819 0.09642 0.56088 0.08217 58576.322616 0.000382 0.41526 0.07027 0.98485 0 2.16536 0.19889 1.84742 0.16969 0.89918 0.12780 0.76707 0.10902 58576.323446 0.000448 0.30647 0.04988 0.98710 0 2.50528 0.20183 2.13641 0.17211 0.76779 0.10858 0.65468 0.09259 58576.324279 0.000385 0.40421 0.06837 0.97744 0 2.23468 0.20734 1.90588 0.17683 0.90328 0.12774 0.77051 0.10897 58576.325084 0.000420 0.37450 0.06300 0.98621 0 2.17524 0.19332 1.85368 0.16475 0.81462 0.11636 0.69420 0.09916 58576.325937 0.000434 0.34270 0.05645 0.97333 0 2.35900 0.19928 2.00154 0.16908 0.80842 0.11433 0.68607 0.09703 58576.326768 0.000396 0.45308 0.07706 0.97080 0 1.99307 0.19041 1.69123 0.16158 0.90302 0.12707 0.76483 0.10762 58576.327711 0.000547 0.35037 0.05685 0.94180 0 1.94314 0.15933 1.65602 0.13579 0.68081 0.09532 0.58021 0.08124 58576.328631 0.000373 0.39892 0.06694 0.96899 0 2.37065 0.21410 2.01201 0.18171 0.94570 0.13375 0.80133 0.11333 58576.329765 0.000761 0.38217 0.04583 0.97719 0 2.36205 0.14978 1.99788 0.12669 0.90269 0.09188 0.76300 0.07766
