/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 55547.411678 0.000901 0.65526 0.19005 0.98387 1 0.24117 0.04419 0.19933 0.03652 0.15803 0.03553 0.13049 0.02933 55547.413726 0.001148 0.54545 0.15136 0.93671 1 0.24028 0.03909 0.19688 0.03203 0.13106 0.02946 0.10756 0.02418 55547.415760 0.000886 0.76651 0.22532 0.98361 1 0.22182 0.04368 0.18175 0.03579 0.17003 0.03711 0.14000 0.03055 55547.417764 0.001118 0.50791 0.13911 0.97403 1 0.25427 0.04021 0.21053 0.03329 0.12915 0.02888 0.10667 0.02385 55547.419609 0.000726 0.81126 0.24564 0.98000 1 0.24348 0.04970 0.20000 0.04083 0.19753 0.04417 0.16327 0.03651 55547.421134 0.000799 0.78179 0.23476 0.96364 1 0.23022 0.04552 0.19110 0.03779 0.17998 0.04067 0.14942 0.03377 55547.423444 0.001511 0.74798 0.17012 0.95004 1 0.22087 0.03272 0.18320 0.02714 0.16521 0.02851 0.13683 0.02361
