/* ** ** 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 59236.091372 0.000310 0.11562 0.02800 0.96262 0 9.04943 0.71388 3.32282 0.25900 1.04631 0.23959 0.38398 0.08713 59236.092284 0.000602 0.13203 0.02026 0.95192 0 10.63539 0.55705 3.75617 0.19643 1.40415 0.20250 0.49806 0.07169 59236.093482 0.000596 0.16063 0.02472 0.96602 0 9.03827 0.53013 3.11772 0.18289 1.45185 0.20660 0.50075 0.07123 59236.094425 0.000347 0.08272 0.01954 0.96667 0 11.95915 0.78700 4.10557 0.27011 0.98924 0.22447 0.34095 0.07736 59236.095157 0.000385 0.09584 0.02314 0.93233 0 9.71979 0.67520 3.36197 0.23351 0.93156 0.21537 0.32260 0.07450 59236.096740 0.001198 0.12077 0.01325 0.97109 0 11.20485 0.41004 3.87392 0.14176 1.35323 0.14002 0.46712 0.04833 59236.139430 0.000310 0.12769 0.01963 0.96262 0 8.41868 0.42952 7.54692 0.38500 1.07494 0.15585 0.96429 0.13981 59236.140882 0.001143 0.12663 0.00960 0.98734 0 8.94187 0.22991 8.05515 0.20710 1.13232 0.08078 1.02005 0.07277 59236.142534 0.000509 0.11379 0.01329 0.97159 0 9.61831 0.35783 8.60588 0.32017 1.09449 0.12119 0.97915 0.10844
