/* ** ** 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 55033.178658 0.000741 0.73289 0.21876 1.00000 1 0.26706 0.05280 0.21500 0.04251 0.19573 0.04377 0.15686 0.03508 55033.180415 0.001017 0.74755 0.22235 0.98571 1 0.19251 0.03776 0.15523 0.03044 0.14391 0.03218 0.11594 0.02593 55033.182391 0.000959 0.56026 0.15757 0.96970 1 0.27420 0.04635 0.22222 0.03756 0.15363 0.03453 0.12438 0.02796 55033.184410 0.001060 0.50504 0.13868 0.95890 1 0.28217 0.04497 0.22686 0.03615 0.14251 0.03187 0.11429 0.02556 55033.186560 0.001089 0.55208 0.15492 1.00000 1 0.23952 0.04061 0.19389 0.03287 0.13223 0.02957 0.10667 0.02385 55033.189290 0.001641 0.63961 0.14843 0.98185 1 0.21565 0.03153 0.17371 0.02539 0.13793 0.02486 0.11140 0.02008
