/* ** ** 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 59852.050617 0.000049 0.09036 0.05460 0.98503 0 4.62874 0.82636 3.97129 0.70898 0.41823 0.24147 0.35883 0.20717 59852.051382 0.000697 0.16435 0.03961 0.95833 1 4.25343 0.38244 1.05878 0.09519 0.69904 0.15632 0.17392 0.03889 59852.052820 0.000741 0.17956 0.04396 0.98039 1 3.50910 0.33548 0.88206 0.08433 0.63008 0.14203 0.15881 0.03580 59852.054127 0.000566 0.23212 0.05851 0.97436 1 3.57667 0.39004 0.89588 0.09769 0.83022 0.18866 0.20740 0.04713 59852.055594 0.000901 0.13854 0.03315 0.98387 1 3.75122 0.31918 0.94687 0.08056 0.51968 0.11621 0.13115 0.02933 59852.056930 0.000436 0.32257 0.08416 1.00000 1 3.26368 0.43865 0.82523 0.11091 1.05276 0.23541 0.26667 0.05963 59852.058121 0.000755 0.15407 0.03732 0.96154 1 4.09839 0.36307 1.03049 0.09128 0.63144 0.14234 0.15881 0.03580 59852.059516 0.000639 0.21831 0.05452 0.93182 1 3.50059 0.36270 0.88058 0.09124 0.76422 0.17365 0.19222 0.04368 59852.060750 0.000596 0.21642 0.05341 0.97561 1 3.68516 0.38479 0.92406 0.09648 0.79756 0.17834 0.20000 0.04472 59852.062145 0.000799 0.17283 0.04214 0.96364 1 3.46390 0.32193 0.86637 0.08052 0.59866 0.13496 0.14982 0.03377 59852.064440 0.001496 0.14410 0.02667 0.96965 1 3.74293 0.24474 0.93712 0.06127 0.53937 0.09338 0.13498 0.02337
