/* ** ** 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 54717.578459 0.001874 0.54328 0.15154 1.00000 1 0.14519 0.02420 0.11520 0.01920 0.07888 0.01764 0.06202 0.01387 54717.584938 0.004605 0.35970 0.06730 0.98423 1 0.17457 0.01689 0.13883 0.01343 0.06279 0.01005 0.05000 0.00801 54717.650442 0.006493 0.45873 0.10726 0.96984 1 0.09932 0.01296 0.05500 0.00717 0.04556 0.00884 0.02491 0.00479 54717.720228 0.003355 0.45130 0.10483 0.98161 1 0.13663 0.01776 0.10561 0.01373 0.06166 0.01187 0.04763 0.00917 54717.779212 0.002048 0.47150 0.12762 0.97872 1 0.15160 0.02312 0.12286 0.01874 0.07148 0.01598 0.05797 0.01296 54717.783555 0.002295 0.35624 0.09322 0.98734 1 0.17788 0.02418 0.14366 0.01952 0.06337 0.01417 0.05128 0.01147 54717.788058 0.002208 0.62767 0.15776 0.98365 1 0.13651 0.02132 0.11043 0.01725 0.08568 0.01687 0.06928 0.01364 54717.848649 0.001554 0.69823 0.20389 0.98131 1 0.13461 0.02528 0.10931 0.02053 0.09399 0.02102 0.07619 0.01704 54717.853892 0.003689 0.47306 0.09448 0.98425 1 0.15504 0.01758 0.12564 0.01425 0.07334 0.01206 0.05920 0.00973
