/* ** ** 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 55903.082322 0.000959 0.47460 0.12846 0.98485 1 0.32514 0.04959 0.26060 0.03974 0.15431 0.03451 0.12308 0.02752 55903.084341 0.001060 0.76115 0.18409 0.99795 1 0.28074 0.04508 0.22229 0.03569 0.21368 0.03865 0.16912 0.03058 55903.151089 0.002368 1.24555 0.35592 0.98052 1 0.12604 0.02690 0.05611 0.01196 0.15698 0.02983 0.06983 0.01325 55903.553655 0.001177 0.66347 0.14339 0.97423 1 0.35841 0.04907 0.27570 0.03774 0.23779 0.03976 0.18197 0.03042 55903.617140 0.000654 0.90621 0.28316 1.00000 1 0.24586 0.05365 0.19535 0.04263 0.22280 0.04982 0.17778 0.03975 55903.618287 0.000494 1.47276 0.51974 1.00000 1 0.21033 0.05833 0.16774 0.04652 0.30976 0.06760 0.24706 0.05391 55903.619798 0.001017 0.54911 0.15008 0.97828 1 0.27877 0.04547 0.22235 0.03627 0.15307 0.03357 0.12208 0.02677
