/* ** ** 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 58214.010757 0.000613 0.13584 0.03291 0.99057 0 1.60316 0.13584 1.38001 0.11692 0.21778 0.04943 0.18830 0.04274 58214.012383 0.001013 0.08036 0.01871 0.99429 0 1.65675 0.10750 1.43336 0.09300 0.13314 0.02977 0.11513 0.02574 58214.015039 0.001644 0.09656 0.01768 0.97428 0 1.44728 0.07990 1.25422 0.06924 0.13976 0.02439 0.12119 0.02115 58214.131048 0.000622 0.16884 0.04097 0.97209 0 1.33980 0.12616 1.13549 0.10693 0.22621 0.05058 0.19171 0.04287 58214.132451 0.000781 0.10802 0.02550 0.98519 0 1.66879 0.12606 1.39188 0.10514 0.18027 0.04031 0.15063 0.03368 58214.134028 0.000796 0.12056 0.02893 0.95273 0 1.48587 0.11720 1.25115 0.09868 0.17913 0.04059 0.15111 0.03424 58214.135564 0.000741 0.11525 0.02727 0.98438 0 1.66032 0.12860 1.38566 0.10732 0.19135 0.04279 0.15899 0.03555 58214.136994 0.000689 0.13534 0.03227 0.97059 0 1.54373 0.12763 1.28092 0.10590 0.20893 0.04672 0.17345 0.03878 58214.138091 0.000408 0.21738 0.05436 0.97872 0 1.58116 0.16726 1.31834 0.13945 0.34371 0.07788 0.28689 0.06501 58214.139372 0.000874 0.12226 0.02733 0.97351 0 1.52192 0.11290 1.26668 0.09396 0.18606 0.03924 0.15511 0.03272
