/* ** ** 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 57428.312313 0.000648 0.08944 0.00673 0.97768 0 21.97884 0.46912 20.18233 0.43078 1.96586 0.14175 1.80480 0.13015 57428.313586 0.000625 0.09551 0.00702 0.99537 0 21.38471 0.46850 19.80480 0.43389 2.04241 0.14335 1.89152 0.13276 57428.314816 0.000605 0.09576 0.00714 0.99522 0 21.62226 0.48022 20.02435 0.44474 2.07063 0.14738 1.91760 0.13649 57428.316135 0.000715 0.08154 0.00601 0.98381 0 22.07445 0.44566 20.44348 0.41273 1.79994 0.12765 1.66695 0.11822 57428.317498 0.000648 0.08777 0.00672 0.98214 0 21.79883 0.46559 20.18843 0.43119 1.91333 0.14074 1.77198 0.13034 57428.318759 0.000613 0.09402 0.00700 0.99528 0 21.70883 0.47669 20.10523 0.44148 2.04111 0.14528 1.89034 0.13454 57428.319975 0.000602 0.09634 0.00732 0.99038 0 21.52484 0.47995 19.93529 0.44451 2.07376 0.15073 1.92062 0.13960 57428.321294 0.000718 0.07929 0.00598 0.99597 0 21.69221 0.44171 20.08896 0.40906 1.72005 0.12486 1.59290 0.11563 57428.322793 0.000781 0.09300 0.00635 0.98519 0 21.57768 0.42248 19.98457 0.39129 2.00683 0.13124 1.85867 0.12155
