/* ** ** 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 59544.417374 0.001002 0.70405 0.20305 1.00000 1 0.21514 0.04056 0.17324 0.03266 0.15147 0.03306 0.12174 0.02657 59544.419480 0.001104 0.43550 0.11718 0.97368 1 0.30712 0.04540 0.24809 0.03667 0.13375 0.03007 0.10755 0.02418 59544.421354 0.000770 0.69290 0.20508 1.00000 1 0.26681 0.05135 0.21600 0.04157 0.18488 0.04157 0.15016 0.03376 59544.423024 0.000901 0.86105 0.26521 1.00000 1 0.18319 0.03856 0.14946 0.03146 0.15774 0.03547 0.12836 0.02886 59544.425000 0.001075 0.65329 0.18887 1.00000 1 0.20336 0.03726 0.16609 0.03043 0.13285 0.02971 0.10811 0.02417 59544.427048 0.000973 0.70981 0.20782 0.97015 1 0.21296 0.04025 0.17231 0.03256 0.15116 0.03380 0.12308 0.02752 59544.429967 0.001946 0.76943 0.17206 0.98273 1 0.17470 0.02594 0.14167 0.02104 0.13442 0.02247 0.10904 0.01823
