/* ** ** 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 58248.175675 0.000489 0.32211 0.05260 0.98817 0 2.22538 0.18165 1.85788 0.15164 0.71682 0.10138 0.59980 0.08482 58248.176673 0.000509 0.29417 0.04704 0.97159 0 2.42175 0.18530 2.04611 0.15654 0.71241 0.10004 0.60268 0.08461 58248.177668 0.000486 0.33953 0.05628 0.97619 0 2.12229 0.18032 1.78623 0.15177 0.72058 0.10256 0.60737 0.08644 58248.178635 0.000475 0.32771 0.05400 0.98780 0 2.23075 0.18385 1.89341 0.15605 0.73103 0.10430 0.62036 0.08851 58248.179598 0.000489 0.34358 0.05737 0.98817 0 2.04980 0.17585 1.72536 0.14800 0.70427 0.10090 0.59312 0.08496 58248.180530 0.000443 0.32019 0.05184 0.98693 0 2.49858 0.20303 2.11230 0.17163 0.80002 0.11203 0.67662 0.09475 58248.181569 0.000596 0.23959 0.03774 0.96602 0 2.49150 0.17279 2.10075 0.14567 0.59693 0.08442 0.50335 0.07118 58248.182567 0.000402 0.39340 0.06635 0.98561 0 2.19394 0.19845 1.84500 0.16688 0.86310 0.12285 0.72708 0.10348 58248.183467 0.000498 0.30114 0.04937 0.99419 0 2.28982 0.18265 1.92284 0.15335 0.68954 0.09876 0.57925 0.08297 58248.184346 0.000382 0.41710 0.06954 0.97727 0 2.26690 0.20379 1.91771 0.17240 0.94552 0.13275 0.79890 0.11215 58248.185214 0.000486 0.38251 0.06376 0.96429 0 1.90452 0.16802 1.61619 0.14259 0.72849 0.10303 0.61831 0.08744 58248.186256 0.000556 0.41688 0.06064 0.95833 0 2.08362 0.16557 1.76792 0.14049 0.86862 0.10583 0.73733 0.08983
