/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 59210.195294 0.000634 0.14699 0.01147 0.98630 0 13.49684 0.37000 12.34187 0.33831 1.98394 0.14489 1.81357 0.13246 59210.196584 0.000657 0.14794 0.01149 0.98238 0 13.07695 0.36111 11.93371 0.32950 1.93455 0.14040 1.76465 0.12805 59210.197788 0.000547 0.17529 0.01347 1.00000 0 13.31921 0.39800 12.16282 0.36345 2.33470 0.16532 2.13167 0.15095 59210.198934 0.000599 0.16978 0.01317 0.99034 0 12.58198 0.37073 11.47379 0.33808 2.13612 0.15323 1.94786 0.13971 59210.200201 0.000668 0.15155 0.01188 0.97403 0 12.49114 0.34653 11.49125 0.31879 1.89299 0.13880 1.74198 0.12772 59210.201813 0.000943 0.17375 0.01049 0.97969 0 12.78809 0.29756 11.69794 0.27216 2.22197 0.12374 2.03300 0.11322
