/* ** ** 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 58597.235514 0.000310 0.52298 0.09369 0.99065 0 2.09741 0.22353 1.77898 0.18957 1.09690 0.15794 0.93010 0.13391 58597.236214 0.000391 0.42949 0.07417 0.97778 0 2.04423 0.19501 1.74188 0.16616 0.87797 0.12639 0.74690 0.10754 58597.236978 0.000373 0.53809 0.09559 0.98450 0 1.70850 0.18178 1.45686 0.15501 0.91933 0.13079 0.78458 0.11162 58597.237811 0.000460 0.32864 0.05413 0.95597 0 2.32778 0.19322 1.99497 0.16559 0.76499 0.10883 0.65554 0.09326 58597.238691 0.000420 0.46917 0.08136 0.94483 0 1.82405 0.17859 1.54072 0.15085 0.85579 0.12248 0.72347 0.10354 58597.239484 0.000373 0.51037 0.09019 1.00000 0 1.75872 0.18231 1.50550 0.15606 0.89760 0.12846 0.76834 0.10996 58597.240210 0.000353 0.49275 0.08534 0.95082 0 2.05637 0.20559 1.75618 0.17556 1.01328 0.14331 0.86351 0.12212 58597.240956 0.000394 0.36611 0.06105 0.97794 0 2.46005 0.21732 2.05620 0.18164 0.90066 0.12738 0.75313 0.10651 58597.241740 0.000391 0.38984 0.06547 0.97778 0 2.30312 0.20775 1.96529 0.17728 0.89784 0.12720 0.76606 0.10853 58597.242588 0.000457 0.39732 0.06697 0.98734 0 1.88324 0.17019 1.60818 0.14532 0.74825 0.10645 0.63873 0.09087 58597.243482 0.000437 0.44410 0.07720 0.98013 0 1.79358 0.17465 1.50497 0.14654 0.79653 0.11470 0.66615 0.09591 58597.244324 0.000405 0.39465 0.06714 0.98571 0 2.15772 0.19561 1.80939 0.16400 0.85155 0.12259 0.71443 0.10286 58597.245135 0.000405 0.45563 0.07951 0.97143 0 1.89047 0.18406 1.58244 0.15408 0.86135 0.12474 0.72107 0.10445 58597.246382 0.000842 0.36379 0.04479 0.97251 0 2.13728 0.13718 1.78874 0.11480 0.77753 0.08168 0.65091 0.06837
