/* ** ** 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 58189.325891 0.000477 0.42856 0.07441 0.98182 0 1.67575 0.16030 1.40975 0.13486 0.71816 0.10406 0.60526 0.08769 58189.326849 0.000480 0.38287 0.06424 0.98193 0 1.94363 0.17550 1.60298 0.14472 0.74416 0.10524 0.61452 0.08691 58189.327833 0.000503 0.41161 0.06980 0.97701 0 1.71023 0.15780 1.42399 0.13140 0.70394 0.10015 0.58611 0.08339 58189.328698 0.000362 0.52125 0.09208 0.96800 0 1.89568 0.19635 1.57276 0.16290 0.98812 0.14141 0.81908 0.11724 58189.329392 0.000333 0.62426 0.11420 0.97391 0 1.72514 0.19655 1.42003 0.16178 1.07694 0.15413 0.88490 0.12666 58189.330188 0.000463 0.42251 0.07228 0.94375 0 1.87123 0.17523 1.55535 0.14565 0.79062 0.11319 0.65635 0.09394 58189.331129 0.000477 0.39280 0.06659 0.95758 0 1.91980 0.17439 1.59812 0.14515 0.75409 0.10793 0.62727 0.08978 58189.332034 0.000428 0.40503 0.06855 0.97297 0 2.07540 0.19029 1.70886 0.15668 0.84059 0.11958 0.69193 0.09844 58189.332859 0.000396 0.46698 0.07978 0.98540 0 1.93813 0.18967 1.61506 0.15803 0.90506 0.12674 0.75682 0.10598 58189.333652 0.000396 0.52416 0.09225 0.98540 0 1.70966 0.17709 1.40844 0.14588 0.89614 0.12750 0.73806 0.10500 58189.334491 0.000443 0.48384 0.08403 0.98039 0 1.67112 0.16579 1.38411 0.13730 0.80855 0.11526 0.67056 0.09557 58189.335370 0.000437 0.50602 0.08885 0.96689 0 1.60221 0.16295 1.33947 0.13621 0.81074 0.11606 0.67883 0.09716 58189.336308 0.000501 0.33366 0.06086 0.97688 0 1.75513 0.16100 1.46210 0.13411 0.58561 0.09233 0.48848 0.07701
