/* ** ** 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 60103.161378 0.000359 0.18514 0.01473 0.97581 0 18.96040 0.58318 17.48761 0.53784 3.51040 0.25758 3.23797 0.23758 60103.162121 0.000385 0.17191 0.01350 0.99248 0 18.87828 0.56413 17.33547 0.51794 3.24544 0.23562 2.98042 0.21638 60103.162856 0.000350 0.19233 0.01489 1.00000 0 18.59407 0.58527 17.21594 0.54190 3.57611 0.25287 3.31130 0.23414 60103.163559 0.000353 0.18499 0.01428 1.00000 0 19.40964 0.59620 17.83053 0.54766 3.59057 0.25428 3.30214 0.23386 60103.164262 0.000350 0.18410 0.01481 1.00000 0 18.89817 0.58917 17.51485 0.54605 3.47922 0.25798 3.22456 0.23910 60103.164951 0.000339 0.19562 0.01539 0.99145 0 18.88384 0.60165 17.50530 0.55773 3.69407 0.26574 3.42441 0.24634 60103.165651 0.000362 0.18615 0.01454 0.99200 0 18.55769 0.57696 17.20142 0.53479 3.45443 0.24750 3.20195 0.22941 60103.166378 0.000365 0.17955 0.01427 0.99206 0 18.83190 0.57644 17.45685 0.53435 3.38124 0.24809 3.13435 0.22998 60103.167075 0.000333 0.20289 0.01578 0.99130 0 18.79019 0.60304 17.41744 0.55899 3.81240 0.26999 3.53387 0.25027 60103.167790 0.000382 0.17289 0.01351 1.00000 0 18.68205 0.56146 17.31779 0.52046 3.23003 0.23296 2.99416 0.21595 60103.168507 0.000336 0.19535 0.01516 1.00000 0 19.17759 0.60838 17.77781 0.56397 3.74639 0.26532 3.47294 0.24595 60103.169474 0.000631 0.19285 0.01141 0.99226 0 18.22443 0.43246 16.84548 0.39974 3.51450 0.19045 3.24673 0.17594
