/* ** ** 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 58250.167358 0.000443 0.57062 0.08380 0.97386 0 2.07321 0.18472 1.73979 0.15500 1.18302 0.13810 0.99135 0.11572 58250.168200 0.000399 0.45645 0.07905 0.95652 0 1.95495 0.18794 1.63299 0.15698 0.89235 0.12854 0.74665 0.10755 58250.169004 0.000405 0.41339 0.07214 0.99286 0 2.02985 0.19460 1.69941 0.16292 0.83913 0.12236 0.70133 0.10228 58250.169811 0.000402 0.41420 0.07109 0.97842 0 2.13495 0.19928 1.75107 0.16343 0.88429 0.12736 0.72469 0.10438 58250.170561 0.000347 0.46369 0.07970 0.96667 0 2.24919 0.21687 1.84934 0.17829 1.04293 0.14841 0.85888 0.12221 58250.171325 0.000417 0.38746 0.06496 1.00000 0 2.16681 0.19504 1.79433 0.16153 0.83956 0.11874 0.69560 0.09837 58250.172057 0.000315 0.60679 0.11022 0.99083 0 1.85284 0.21118 1.52996 0.17435 1.12428 0.15901 0.92747 0.13116 58250.172795 0.000422 0.40382 0.06833 0.96575 0 2.11916 0.19398 1.74959 0.16012 0.85577 0.12178 0.70660 0.10054 58250.173611 0.000394 0.45722 0.07913 0.98529 0 1.98901 0.19595 1.62596 0.16018 0.90941 0.12940 0.74351 0.10579 58250.174403 0.000399 0.44431 0.07616 0.94928 0 2.06263 0.19718 1.71582 0.16401 0.91645 0.13039 0.76054 0.10821 58250.175211 0.000408 0.43999 0.07595 0.96454 0 1.98348 0.18862 1.64876 0.15678 0.87270 0.12573 0.72469 0.10438 58250.176012 0.000394 0.45210 0.07301 0.98529 0 2.27952 0.20826 1.87870 0.17161 1.03058 0.13725 0.84816 0.11294
