/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 56490.011144 0.000489 0.13081 0.03303 0.97633 0 2.06356 0.17273 1.76183 0.14746 0.26994 0.06431 0.22971 0.05469 56490.012076 0.000443 0.18378 0.04483 0.96078 0 1.75506 0.17097 1.48356 0.14453 0.32254 0.07212 0.27256 0.06095 56490.012918 0.000399 0.16769 0.04118 0.98551 0 2.05653 0.19214 1.73302 0.16191 0.34487 0.07831 0.29063 0.06600 56490.013716 0.000399 0.19259 0.04712 0.97101 0 1.82457 0.18106 1.55024 0.15383 0.35140 0.07858 0.29901 0.06686 56490.014674 0.000558 0.12960 0.03007 0.97409 0 2.03957 0.16066 1.73574 0.13673 0.26432 0.05768 0.22378 0.04883 56490.015574 0.000341 0.20275 0.04990 0.97458 0 2.02591 0.20832 1.71570 0.17643 0.41075 0.09185 0.34841 0.07791 56490.016451 0.000535 0.13314 0.03219 0.97838 0 1.92756 0.15978 1.63534 0.13555 0.25664 0.05829 0.21837 0.04959 56490.017301 0.000315 0.20397 0.05155 0.98165 0 2.10080 0.21739 1.78831 0.18505 0.42849 0.09881 0.36434 0.08404 56490.017921 0.000304 0.21213 0.05375 0.96190 0 2.15916 0.22639 1.81968 0.19079 0.45802 0.10564 0.38598 0.08903 56490.018710 0.000486 0.13611 0.03291 0.97619 0 2.08695 0.17299 1.77306 0.14696 0.28405 0.06451 0.24101 0.05473 56490.019547 0.000350 0.25155 0.06304 0.98347 0 1.55485 0.17587 1.34443 0.15206 0.39113 0.08746 0.33670 0.07529 56490.020719 0.000822 0.17728 0.03125 0.97735 0 1.78113 0.12276 1.54700 0.10662 0.31576 0.05122 0.27426 0.04449 56490.078073 0.000616 0.12281 0.02998 0.97183 0 1.79046 0.14326 1.53000 0.12243 0.21988 0.05071 0.18837 0.04344 56490.079227 0.000538 0.14585 0.03498 0.97312 0 1.76334 0.15304 1.51227 0.13124 0.25719 0.05751 0.22136 0.04950 56490.080165 0.000399 0.17217 0.04167 0.95652 0 2.04298 0.18921 1.76305 0.16329 0.35173 0.07865 0.30354 0.06787 56490.081088 0.000524 0.14591 0.03549 0.97238 0 1.78382 0.15551 1.53930 0.13419 0.26028 0.05910 0.22460 0.05100 56490.082138 0.000527 0.15166 0.03640 0.98352 0 1.71837 0.14980 1.47943 0.12897 0.26060 0.05827 0.22384 0.05005 56490.083026 0.000362 0.21817 0.05400 0.99200 0 1.72083 0.18263 1.48120 0.15719 0.37544 0.08395 0.32312 0.07225 56490.083721 0.000333 0.23624 0.05885 0.96522 0 1.77054 0.19435 1.52794 0.16772 0.41828 0.09353 0.36096 0.08071 56490.084502 0.000448 0.16055 0.03870 0.97419 0 1.91527 0.17243 1.65263 0.14878 0.30750 0.06876 0.26534 0.05933 56490.085509 0.000558 0.18591 0.03977 0.97409 0 1.72692 0.14744 1.49030 0.12724 0.32106 0.06296 0.27706 0.05434
