/* ** ** 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 56498.490861 0.000437 1.03298 0.32582 1.00000 0 0.35916 0.08180 0.26971 0.06142 0.37101 0.08096 0.27861 0.06080 56498.491821 0.000524 0.63460 0.18612 0.97790 0 0.46980 0.08683 0.34947 0.06459 0.29813 0.06789 0.22247 0.05067 56498.492973 0.000628 0.64925 0.18812 0.96774 0 0.39035 0.07127 0.29034 0.05301 0.25344 0.05702 0.18970 0.04268 56498.494275 0.000674 0.69121 0.20383 0.96137 0 0.34300 0.06483 0.25497 0.04818 0.23708 0.05366 0.17682 0.04002 56498.495505 0.000556 1.03055 0.33016 0.94792 0 0.28681 0.06580 0.21384 0.04906 0.29557 0.06609 0.22015 0.04923 56498.496561 0.000501 0.98584 0.31468 0.94798 0 0.33224 0.07568 0.24766 0.05640 0.32754 0.07324 0.24431 0.05463 56498.497594 0.000532 0.73560 0.22067 0.95109 0 0.40976 0.08067 0.30780 0.06059 0.30142 0.06823 0.22633 0.05123 56498.498887 0.000761 0.66197 0.19382 0.96198 0 0.32252 0.06095 0.23972 0.04530 0.21350 0.04774 0.15837 0.03541 56498.500184 0.000535 1.22363 0.41268 0.95676 0 0.24699 0.06175 0.18421 0.04605 0.30222 0.06841 0.22377 0.05065 56498.501373 0.000654 1.17861 0.39344 0.95133 0 0.21276 0.05273 0.15889 0.03938 0.25077 0.05608 0.18636 0.04167
