/* ** ** 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 60061.432358 0.000318 0.16044 0.01285 1.00000 0 23.58063 0.68767 21.87929 0.63805 3.78322 0.28217 3.50992 0.26178 60061.432977 0.000301 0.17317 0.01361 0.99038 0 24.03187 0.72201 22.04364 0.66227 4.16156 0.30225 3.81922 0.27733 60061.433561 0.000284 0.17397 0.01339 0.98980 0 25.76896 0.76530 23.76957 0.70592 4.48291 0.31834 4.13245 0.29341 60061.434186 0.000341 0.15693 0.01204 0.98305 0 23.99156 0.67913 22.03809 0.62374 3.76491 0.26838 3.45715 0.24646 60061.434863 0.000336 0.15572 0.01201 1.00000 0 23.83704 0.68003 21.99854 0.62750 3.71198 0.26597 3.42261 0.24524 60061.435523 0.000324 0.16026 0.01242 1.00000 0 23.84908 0.68686 22.12848 0.63731 3.82207 0.27498 3.54647 0.25515 60061.436162 0.000315 0.15538 0.01197 1.00000 0 25.46939 0.72230 23.44803 0.66492 3.95755 0.28357 3.64241 0.26099 60061.436828 0.000350 0.14747 0.01146 0.99174 0 24.25169 0.67267 22.21414 0.61609 3.57647 0.25973 3.27816 0.23804 60061.437522 0.000344 0.15360 0.01197 0.99160 0 23.67291 0.67188 21.75483 0.61738 3.63609 0.26398 3.33372 0.24207 60061.438191 0.000324 0.16913 0.01303 0.98214 0 23.59147 0.69350 21.75921 0.63962 3.99001 0.28419 3.68380 0.26233 60061.439010 0.000495 0.16240 0.01017 0.99707 0 23.90444 0.56615 21.87488 0.51801 3.88215 0.22518 3.55165 0.20604
