/* ** ** 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 54706.011848 0.001322 0.61192 0.17124 0.99891 1 0.18856 0.03303 0.15098 0.02645 0.11538 0.02518 0.09241 0.02017 54706.163786 0.035142 0.45106 0.09713 0.07229 1 0.20734 0.02515 0.15645 0.01889 0.09352 0.01664 0.07296 0.01294 54706.200846 0.001917 0.63369 0.15419 0.99059 1 0.16366 0.02508 0.13506 0.02070 0.10371 0.01960 0.08565 0.01619 54706.268607 0.001075 0.84930 0.25968 0.97297 1 0.16493 0.03439 0.13143 0.02740 0.14008 0.03132 0.11111 0.02485 54706.271992 0.002310 0.45748 0.10073 0.96698 1 0.21344 0.02627 0.17060 0.02100 0.09764 0.01783 0.07805 0.01425 54706.568137 0.238082 0.56264 0.10172 0.03320 1 0.12082 0.01304 0.06710 0.00707 0.06798 0.00986 0.03602 0.00515
