/* ** ** 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 55005.595043 0.001002 0.54282 0.15155 0.98551 1 0.27160 0.04540 0.21758 0.03637 0.14743 0.03297 0.11765 0.02631 55005.597193 0.001148 0.42875 0.11494 0.98734 1 0.29872 0.04417 0.24105 0.03564 0.12807 0.02864 0.10257 0.02293 55005.599212 0.000872 0.55801 0.15744 0.98333 1 0.30080 0.05175 0.24215 0.04166 0.16785 0.03753 0.13559 0.03032 55005.601042 0.000959 0.61108 0.17822 0.98485 1 0.24794 0.04607 0.20001 0.03716 0.15151 0.03406 0.12246 0.02753 55005.602625 0.000625 1.34418 0.45636 0.97674 1 0.18416 0.04790 0.14900 0.03874 0.24755 0.05402 0.20000 0.04364 55005.604049 0.000799 0.69694 0.20348 0.98182 1 0.26242 0.04926 0.21260 0.03991 0.18289 0.04090 0.14815 0.03313 55005.605676 0.000828 0.78259 0.23278 0.96491 1 0.22985 0.04508 0.18572 0.03642 0.17988 0.04022 0.14546 0.03252 55005.608101 0.001598 0.67027 0.14492 0.99842 1 0.24464 0.03380 0.19887 0.02748 0.16397 0.02727 0.13330 0.02217
