/* ** ** 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 53680.119996 0.000988 0.21262 0.01665 0.98529 1 27.92601 0.91052 5.61095 0.18294 5.93767 0.42273 1.19314 0.08494 53680.121840 0.000857 0.23588 0.01880 1.00000 1 28.24528 0.99054 5.68569 0.19939 6.66264 0.47674 1.34136 0.09598 53680.123613 0.000915 0.22556 0.01764 0.98413 1 28.77995 0.96597 5.80149 0.19472 6.49167 0.45869 1.30871 0.09247 53680.125385 0.000857 0.24437 0.01959 1.00000 1 27.13105 0.96917 5.47309 0.19551 6.62990 0.47594 1.33738 0.09601 53680.126547 0.000305 0.17191 0.02638 1.00000 1 27.81222 1.66972 5.60921 0.33675 4.78119 0.67518 0.96399 0.13613 53680.127883 0.001031 0.20367 0.01604 0.98592 1 27.45271 0.88645 5.54530 0.17906 5.59141 0.40168 1.12958 0.08115 53680.130498 0.001583 0.22946 0.01403 0.98904 1 26.90792 0.71095 5.42495 0.14334 6.17439 0.34035 1.24494 0.06862
