/* ** ** 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 56491.148021 0.000787 0.53283 0.14941 0.98529 0 0.40303 0.06742 0.27757 0.04642 0.21475 0.04833 0.14865 0.03344 56491.149506 0.000697 0.85311 0.26300 0.95436 0 0.29818 0.06285 0.20185 0.04254 0.25438 0.05723 0.17321 0.03897 56491.150993 0.000790 0.59560 0.16989 0.97802 0 0.36543 0.06408 0.25058 0.04394 0.21765 0.04896 0.14921 0.03357 56491.152677 0.000894 0.58030 0.16418 0.96117 0 0.33847 0.05805 0.23011 0.03946 0.19641 0.04420 0.13413 0.03018 56491.154210 0.000639 0.78846 0.23706 0.98190 0 0.34468 0.06927 0.23516 0.04726 0.27176 0.06077 0.18464 0.04129 56491.155579 0.000729 0.61647 0.17638 0.95635 0 0.39357 0.06958 0.26823 0.04742 0.24262 0.05458 0.16530 0.03719 56491.156846 0.000538 0.71277 0.21496 0.99462 0 0.43378 0.08508 0.29595 0.05804 0.30918 0.07084 0.21163 0.04849 56491.158206 0.000822 0.58591 0.15423 0.96831 0 0.42086 0.06760 0.28640 0.04600 0.24659 0.05142 0.16755 0.03494
