/* ** ** 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 57668.207326 0.000465 0.50727 0.13776 1.00000 1 2.03149 0.32374 0.51239 0.08165 1.03051 0.22661 0.26069 0.05731 57668.208111 0.000320 0.91407 0.28336 0.95455 1 1.63141 0.35028 0.41629 0.08938 1.49123 0.33345 0.38096 0.08518 57668.208793 0.000363 0.60008 0.17252 0.96000 1 2.15929 0.38546 0.55148 0.09845 1.29575 0.29201 0.33092 0.07458 57668.209679 0.000523 0.33935 0.08856 0.94444 1 2.69288 0.35430 0.68730 0.09043 0.91384 0.20596 0.23359 0.05264 57668.210580 0.000378 0.32155 0.08303 1.00000 1 3.77208 0.48699 0.96001 0.12394 1.21292 0.27124 0.30769 0.06880 57668.211350 0.000392 0.47923 0.12819 0.96296 1 2.63913 0.40212 0.67024 0.10212 1.26476 0.27804 0.32085 0.07054 57668.240110 0.028368 0.67771 0.13963 0.04393 1 0.93769 0.12268 0.29591 0.03732 0.63548 0.10114 0.20198 0.03096 57668.269553 0.001075 0.56686 0.15555 0.98649 1 0.46201 0.07618 0.20219 0.03334 0.26189 0.05745 0.11452 0.02512 57668.271863 0.001235 0.43712 0.11523 1.00000 1 0.51121 0.07555 0.22667 0.03350 0.22346 0.04878 0.09882 0.02157 57668.274536 0.001438 0.31142 0.08062 0.97980 1 0.59989 0.07699 0.26127 0.03352 0.18682 0.04200 0.08206 0.01845 57668.277005 0.001031 0.55073 0.15428 0.97183 1 0.47548 0.07949 0.20812 0.03479 0.26186 0.05886 0.11536 0.02593 57668.279387 0.001351 0.41264 0.10887 0.98925 1 0.49986 0.07326 0.21767 0.03189 0.20626 0.04525 0.09087 0.01993 57668.282031 0.001293 0.56562 0.13763 0.97861 1 0.50846 0.07516 0.21857 0.03230 0.28760 0.05558 0.12354 0.02387
