/* ** ** 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 56327.140442 0.000310 0.13997 0.01070 0.99065 0 30.04345 0.79896 26.76971 0.71182 4.20510 0.30131 3.74543 0.26838 56327.141110 0.000359 0.11165 0.00859 0.99194 0 32.05082 0.77067 28.53777 0.68615 3.57852 0.26158 3.18328 0.23271 56327.141813 0.000344 0.11942 0.00906 0.99160 0 31.51606 0.77874 28.32850 0.69998 3.76371 0.27009 3.38304 0.24277 56327.142618 0.000460 0.14283 0.00882 0.98815 0 30.85802 0.66985 27.72955 0.60194 4.40750 0.25493 3.96065 0.22909 56327.341548 0.000738 0.11810 0.00895 0.68059 0 22.98986 0.56768 19.36110 0.47798 2.71510 0.19445 2.28797 0.16390 56327.343027 0.000741 0.11901 0.00730 0.97153 0 24.43846 0.48215 20.75135 0.40941 2.90834 0.16882 2.46986 0.14337 56327.607231 0.000480 0.12986 0.00999 1.00000 0 20.83592 0.54115 18.32922 0.47598 2.70574 0.19589 2.38242 0.17246 56327.608157 0.000446 0.15040 0.01143 0.98701 0 19.97490 0.55120 17.61042 0.48593 3.00418 0.21274 2.65049 0.18769 56327.609028 0.000425 0.14657 0.01156 0.99320 0 20.54088 0.56860 18.22812 0.50458 3.01075 0.22225 2.67187 0.19724 56327.609922 0.000469 0.14508 0.01079 0.98556 0 20.79372 0.54780 18.45644 0.48623 3.01676 0.20977 2.67777 0.18620
