/* ** ** 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 55503.304674 0.001060 0.70554 0.20570 0.95890 1 0.19993 0.03740 0.16223 0.03035 0.14106 0.03154 0.11429 0.02556 55503.306751 0.001017 0.61566 0.17549 0.98571 1 0.23215 0.04104 0.18824 0.03328 0.14293 0.03196 0.11594 0.02593 55503.308930 0.001162 0.72438 0.21407 1.00000 1 0.16984 0.03282 0.13794 0.02665 0.12303 0.02751 0.10000 0.02236 55503.311007 0.000915 0.62468 0.17916 1.00000 1 0.25003 0.04491 0.20328 0.03651 0.15619 0.03492 0.12698 0.02839 55503.312764 0.000842 1.01197 0.31779 1.00000 1 0.17640 0.03945 0.14286 0.03194 0.17851 0.03936 0.14342 0.03162 55503.315481 0.001874 0.54064 0.12554 0.97280 1 0.20980 0.02905 0.17035 0.02359 0.11342 0.02114 0.09211 0.01717 55503.373394 0.001031 0.48727 0.13349 1.00000 1 0.29416 0.04652 0.23189 0.03666 0.14333 0.03206 0.11268 0.02520 55503.375138 0.000712 0.85239 0.26337 1.00000 1 0.24537 0.05232 0.19131 0.04079 0.20915 0.04677 0.16327 0.03651 55503.376721 0.000872 0.72667 0.21124 0.93333 1 0.25011 0.04645 0.19661 0.03651 0.18175 0.04064 0.14286 0.03194 55503.379074 0.001482 0.60142 0.15545 0.97742 1 0.20433 0.03239 0.16008 0.02538 0.12288 0.02509 0.09629 0.01966 55503.442157 0.001046 0.53150 0.14918 1.00000 1 0.26142 0.04434 0.20835 0.03533 0.13894 0.03107 0.11111 0.02485 55503.444132 0.000930 0.49916 0.13838 1.00000 1 0.30823 0.05000 0.24918 0.04042 0.15386 0.03459 0.12436 0.02796 55503.446122 0.001060 0.43834 0.11332 0.99692 1 0.34116 0.04988 0.27587 0.04033 0.14954 0.03188 0.12092 0.02578
