/* ** ** 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 58520.462266 0.000399 0.42999 0.07270 0.97826 0 2.02590 0.18948 1.74776 0.16346 0.87112 0.12270 0.75293 0.10605 58520.463151 0.000486 0.32658 0.05376 0.97024 0 2.18596 0.17777 1.87078 0.15213 0.71390 0.10217 0.60808 0.08703 58520.464039 0.000402 0.39600 0.06744 0.97122 0 2.18170 0.19842 1.84138 0.16747 0.86395 0.12440 0.73032 0.10515 58520.464899 0.000457 0.40673 0.06785 0.96203 0 1.94585 0.17637 1.65366 0.14988 0.79144 0.11083 0.67217 0.09412 58520.465726 0.000370 0.41924 0.07171 0.97656 0 2.23018 0.21177 1.89388 0.17985 0.93498 0.13301 0.79714 0.11340 58520.466586 0.000489 0.38529 0.06481 1.00000 0 1.80967 0.16480 1.53490 0.13977 0.69724 0.09861 0.59270 0.08382 58520.467459 0.000385 0.43390 0.07550 0.99248 0 2.03445 0.19613 1.71238 0.16508 0.88275 0.12786 0.74294 0.10761 58520.468229 0.000385 0.46580 0.08129 0.97744 0 1.92596 0.19226 1.63614 0.16335 0.89711 0.12842 0.76244 0.10912 58520.468978 0.000365 0.48015 0.08366 0.98413 0 1.97904 0.19670 1.66480 0.16546 0.95023 0.13599 0.79934 0.11440 58520.469742 0.000399 0.47841 0.08290 0.97101 0 1.84014 0.18201 1.55469 0.15376 0.88034 0.12525 0.74360 0.10579 58520.470587 0.000446 0.48836 0.08336 0.96753 0 1.68528 0.16582 1.42392 0.14008 0.82303 0.11479 0.69563 0.09702 58520.471557 0.000524 0.34296 0.05698 0.97790 0 1.94287 0.16677 1.64349 0.14107 0.66632 0.09478 0.56295 0.08009 58520.472396 0.000315 0.54562 0.09678 0.96330 0 2.02299 0.21200 1.73543 0.18185 1.10379 0.15796 0.94398 0.13510 58520.473504 0.000793 0.31982 0.04224 0.97080 0 2.14001 0.13906 1.80804 0.11748 0.68443 0.07869 0.57956 0.06663
