/* ** ** Swift/XRT hardness ratio for PG 1553+113. ** 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 55107.583139 0.005752 0.14055 0.02421 0.98377 1 0.59880 0.03640 0.28239 0.01714 0.08416 0.01356 0.03984 0.00641 55107.644520 0.001874 0.14324 0.03426 0.97674 1 0.54618 0.04634 0.44286 0.03757 0.07823 0.01749 0.06349 0.01420 55107.650258 0.003864 0.11058 0.02094 0.99624 1 0.51951 0.03125 0.42321 0.02546 0.05745 0.01032 0.04679 0.00840 55107.716639 0.005563 0.15173 0.03418 0.99109 1 0.45840 0.03790 0.15750 0.01302 0.06955 0.01457 0.02413 0.00505 55107.780561 0.002469 0.12441 0.02972 0.99412 1 0.47169 0.03811 0.37927 0.03065 0.05868 0.01319 0.04710 0.01059 55107.785615 0.002556 0.18613 0.03833 0.98377 1 0.43189 0.03532 0.34752 0.02842 0.08039 0.01519 0.06469 0.01222
