/* ** ** 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 54886.488197 0.000952 0.47392 0.04101 0.98480 0 3.02385 0.14845 2.59214 0.12725 1.43308 0.10211 1.22848 0.08752 54886.489461 0.000312 0.43008 0.07436 0.97222 0 2.51330 0.23718 2.17140 0.20491 1.08091 0.15659 0.93387 0.13529 54886.490182 0.000408 0.37916 0.05393 0.98582 0 3.02747 0.22676 2.60711 0.19526 1.14790 0.13879 0.99067 0.11978 54886.490885 0.000295 0.37962 0.06360 0.99020 0 3.01672 0.26684 2.59975 0.22996 1.14522 0.16293 0.98653 0.14035 54886.491481 0.000301 0.40637 0.06878 0.99038 0 2.78035 0.25381 2.40400 0.21945 1.12986 0.16103 0.97657 0.13918 54886.492083 0.000301 0.45657 0.07858 0.98077 0 2.51134 0.24321 2.14112 0.20735 1.14660 0.16314 0.97685 0.13898 54886.493440 0.001056 0.44792 0.03856 0.98904 0 2.85627 0.13716 2.45706 0.11799 1.27939 0.09142 1.09965 0.07858 54886.495601 0.001105 0.43278 0.03734 0.97644 0 2.86942 0.13736 2.44331 0.11696 1.24183 0.08915 1.06003 0.07609 54886.497135 0.000428 0.36753 0.05109 0.97973 0 3.12517 0.22528 2.68612 0.19363 1.14859 0.13651 0.98748 0.11735 54886.498501 0.000938 0.48814 0.04263 0.97840 0 2.99874 0.15051 2.56251 0.12860 1.46382 0.10461 1.25228 0.08948 54886.499733 0.000295 0.40113 0.06886 0.99020 0 2.85105 0.26270 2.42185 0.22313 1.14363 0.16566 0.97085 0.14064 54886.500691 0.000663 0.38306 0.04229 0.98690 0 3.12306 0.18141 2.66890 0.15501 1.19631 0.11232 1.02311 0.09605
