/* ** ** 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 55512.003660 0.001336 0.54640 0.15238 0.67881 1 0.28595 0.04766 0.23434 0.03906 0.15624 0.03494 0.12810 0.02864 55512.006158 0.001162 0.47803 0.13008 0.97500 1 0.26169 0.04058 0.21435 0.03324 0.12510 0.02797 0.10256 0.02293 55512.008555 0.001235 0.47971 0.13243 0.98824 1 0.24122 0.03865 0.19748 0.03164 0.11572 0.02601 0.09476 0.02130 55512.010763 0.000973 0.56754 0.15506 0.95522 1 0.28174 0.04632 0.23125 0.03802 0.15990 0.03489 0.13125 0.02864 55512.012927 0.001191 0.42639 0.11562 1.00000 1 0.27646 0.04141 0.22683 0.03397 0.11788 0.02664 0.09658 0.02183 55512.015382 0.001264 0.53775 0.12955 0.98439 1 0.28532 0.04076 0.23333 0.03333 0.15343 0.02976 0.12516 0.02428
