/* ** ** 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 58141.509697 0.000451 0.41030 0.07007 0.98077 0 1.81986 0.16694 1.56563 0.14363 0.74669 0.10755 0.64421 0.09278 58141.510695 0.000547 0.36213 0.06033 0.96825 0 1.74480 0.15117 1.50380 0.13029 0.63185 0.08990 0.54444 0.07746 58141.511664 0.000422 0.41087 0.06994 0.99315 0 1.95318 0.18244 1.67088 0.15606 0.80250 0.11419 0.68712 0.09776 58141.512506 0.000420 0.38921 0.06530 0.98621 0 2.09347 0.18608 1.79227 0.15929 0.81479 0.11595 0.69673 0.09913 58141.513270 0.000344 0.60714 0.11040 0.98319 0 1.62649 0.18416 1.40000 0.15850 0.98750 0.14051 0.85156 0.12116 58141.513999 0.000385 0.46807 0.08053 0.96992 0 1.93836 0.18989 1.65963 0.16256 0.90729 0.12832 0.77649 0.10981 58141.514677 0.000292 0.20492 0.05055 1.00000 0 2.22862 0.23214 1.92486 0.20046 0.45668 0.10212 0.39670 0.08870 58141.515828 0.000859 0.43811 0.05408 0.96040 0 1.76614 0.12003 1.52629 0.10371 0.77377 0.07972 0.66863 0.06889 58141.777094 0.000492 0.37618 0.06236 0.99412 0 1.84758 0.16143 1.60098 0.13989 0.69503 0.09791 0.60138 0.08471 58141.778095 0.000509 0.36129 0.06040 0.98295 0 1.83196 0.15815 1.58479 0.13681 0.66186 0.09477 0.57279 0.08200 58141.779128 0.000524 0.34258 0.05582 0.98895 0 1.94721 0.16217 1.67160 0.13921 0.66708 0.09342 0.57078 0.07993 58141.780268 0.000616 0.34152 0.05600 0.97183 0 1.64704 0.13670 1.41725 0.11762 0.56249 0.07955 0.48390 0.06843 58141.781347 0.000463 0.39777 0.06743 1.00000 0 1.81518 0.16475 1.56327 0.14188 0.72202 0.10338 0.61933 0.08866 58141.782120 0.000310 0.28488 0.07161 0.99065 0 1.58907 0.18912 1.37234 0.16333 0.45270 0.10023 0.39182 0.08676 58141.783214 0.000784 0.40781 0.05524 0.96679 0 1.69028 0.12448 1.45456 0.10712 0.68931 0.07836 0.59436 0.06756
