/* ** ** 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 55211.363803 0.000417 0.26233 0.00949 1.00000 0 56.70475 0.93394 52.45774 0.86394 14.87509 0.47891 13.75723 0.44295 55211.364631 0.000411 0.27174 0.00986 1.00000 0 55.88233 0.93696 51.48038 0.86304 15.18556 0.48840 13.97921 0.44964 55211.365464 0.000422 0.25830 0.00931 1.00000 0 56.75150 0.92482 52.74308 0.85950 14.65905 0.47102 13.62366 0.43775 55211.366289 0.000402 0.27338 0.01002 1.00000 0 55.68574 0.94020 51.75332 0.87381 15.22364 0.49537 14.14858 0.46039 55211.367102 0.000411 0.26482 0.00960 1.00000 0 56.77341 0.94096 52.76323 0.87449 15.03449 0.48501 13.97254 0.45075 55211.367906 0.000394 0.27886 0.01015 1.00000 0 56.45998 0.95880 52.22779 0.88691 15.74461 0.50697 14.56648 0.46901 55211.368708 0.000408 0.27091 0.00987 1.00000 0 55.66307 0.93738 51.73178 0.87117 15.07985 0.48749 14.01480 0.45306 55211.369498 0.000382 0.29565 0.01075 1.00000 0 55.21138 0.96408 51.31258 0.89600 16.32309 0.52056 15.17042 0.48380 55211.370276 0.000396 0.27465 0.01005 1.00000 0 56.37904 0.95589 52.39815 0.88840 15.48465 0.50184 14.39129 0.46641 55211.371104 0.000431 0.25546 0.00916 1.00000 0 56.43720 0.91757 52.45164 0.85277 14.41738 0.46049 13.39924 0.42797 55211.371943 0.000408 0.27001 0.00984 0.99291 0 56.33582 0.94184 52.35725 0.87533 15.21099 0.49267 14.13676 0.45788 55211.372750 0.000399 0.27548 0.01008 1.00000 0 55.96001 0.94957 52.00876 0.88252 15.41559 0.49956 14.32712 0.46429 55211.373526 0.000376 0.28934 0.01057 1.00000 0 56.93451 0.98777 52.64715 0.91338 16.47337 0.52962 15.24242 0.49004 55211.374449 0.000547 0.26930 0.00850 1.00000 0 55.77879 0.80789 51.83615 0.75078 15.02128 0.42124 13.95953 0.39147
