/* ** ** 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 54715.252951 0.001264 0.76144 0.22650 0.96552 1 0.16096 0.03157 0.12530 0.02457 0.12256 0.02741 0.09524 0.02130 54715.257120 0.002905 0.32413 0.08392 0.98500 1 0.16115 0.02071 0.12472 0.01602 0.05223 0.01174 0.04041 0.00908 54715.291442 0.031418 0.34762 0.09070 0.07244 1 0.18667 0.02473 0.14646 0.01940 0.06489 0.01459 0.05081 0.01142 54715.325315 0.002455 0.36558 0.08964 0.98615 1 0.19321 0.02462 0.15105 0.01925 0.07063 0.01480 0.05496 0.01151 54715.387756 0.002266 0.36340 0.09568 0.98077 1 0.17901 0.02488 0.14357 0.01996 0.06505 0.01455 0.05229 0.01169 54715.392230 0.002208 0.52070 0.13704 0.97150 1 0.14204 0.02192 0.11454 0.01767 0.07396 0.01577 0.05959 0.01271 54715.454063 0.001670 0.58246 0.16327 0.95652 1 0.15723 0.02658 0.12500 0.02113 0.09158 0.02048 0.07273 0.01626 54715.458769 0.003036 0.63941 0.14758 0.98398 1 0.11868 0.01721 0.09435 0.01368 0.07589 0.01363 0.06030 0.01083 54715.552785 0.033494 0.41643 0.08398 0.18243 1 0.14686 0.01604 0.08815 0.00921 0.06116 0.01037 0.03613 0.00586 54715.588879 0.002600 0.26296 0.06633 0.99441 1 0.20881 0.02438 0.17138 0.02001 0.05491 0.01228 0.04494 0.01005
