/* ** ** 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 56389.658140 0.001047 0.35582 0.09280 0.97514 0 0.43508 0.05839 0.31833 0.04272 0.15481 0.03462 0.11350 0.02538 56389.659755 0.000567 0.52975 0.14809 0.97449 0 0.53618 0.08996 0.39596 0.06643 0.28405 0.06351 0.20977 0.04691 56389.661366 0.001045 0.35312 0.09214 0.96953 0 0.43891 0.05903 0.32415 0.04360 0.15499 0.03466 0.11448 0.02560 56389.663114 0.000703 0.53356 0.14969 0.96708 0 0.43016 0.07211 0.31776 0.05327 0.22952 0.05163 0.16954 0.03814 56389.664405 0.000587 0.40977 0.10938 0.96059 0 0.67880 0.09896 0.50135 0.07309 0.27815 0.06220 0.20547 0.04594 56389.666502 0.001510 0.43454 0.08730 0.95977 0 0.44575 0.04926 0.32920 0.03638 0.19370 0.03250 0.14305 0.02400
