/* ** ** 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 59662.049407 0.000544 0.08288 0.01254 0.97872 0 7.36510 0.30773 6.42880 0.26858 0.61040 0.08875 0.53252 0.07744 59662.050440 0.000489 0.09144 0.01426 0.97041 0 7.30644 0.32173 6.39305 0.28149 0.66813 0.09996 0.58416 0.08740 59662.051274 0.000344 0.05117 0.01216 1.00000 0 7.36957 0.39023 6.39631 0.33868 0.37709 0.08737 0.32752 0.07584 59662.052067 0.000448 0.09770 0.01453 0.98710 0 7.73500 0.34456 6.75996 0.30107 0.75571 0.10727 0.66065 0.09378 59662.053065 0.000550 0.08091 0.01190 0.97368 0 7.58753 0.30603 6.68950 0.26981 0.61394 0.08682 0.54144 0.07657 59662.054190 0.000576 0.08091 0.01224 0.98995 0 6.97016 0.28916 6.14678 0.25500 0.56397 0.08202 0.49738 0.07233 59662.055235 0.000469 0.09778 0.01489 0.98765 0 7.13677 0.32323 6.25828 0.28344 0.69786 0.10148 0.61240 0.08906 59662.056115 0.000411 0.11216 0.01678 0.97887 0 7.32416 0.35742 6.42832 0.31371 0.82148 0.11618 0.72062 0.10191 59662.056867 0.000341 0.13527 0.02068 0.97458 0 7.22131 0.38240 6.36973 0.33730 0.97680 0.14008 0.86153 0.12355 59662.057515 0.000307 0.05834 0.01437 0.97170 0 7.15412 0.39951 6.30504 0.35210 0.41734 0.10015 0.36781 0.08826 59662.058421 0.000599 0.07882 0.01183 0.99034 0 6.75712 0.27851 5.94230 0.24490 0.53262 0.07688 0.46907 0.06770
