/* ** ** 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 60110.901213 0.000460 0.17525 0.01351 0.98742 0 15.83222 0.47055 14.50436 0.43104 2.77467 0.19729 2.54215 0.18072 60110.902171 0.000498 0.16848 0.01310 0.97674 0 15.12412 0.44168 14.00830 0.40910 2.54819 0.18364 2.35998 0.17006 60110.903175 0.000506 0.16606 0.01285 0.98286 0 15.03928 0.43908 13.93534 0.40685 2.49742 0.17900 2.31410 0.16586 60110.904153 0.000472 0.17267 0.01348 0.96933 0 15.60435 0.46246 14.45890 0.42851 2.69445 0.19467 2.49666 0.18038 60110.905099 0.000475 0.17712 0.01380 0.99165 0 15.37415 0.46788 14.24458 0.43350 2.72313 0.19530 2.52300 0.18095 60110.970275 0.000518 0.15978 0.01235 0.99441 0 15.16584 0.43549 13.93944 0.40027 2.42323 0.17381 2.22722 0.15975 60110.971299 0.000506 0.16559 0.01282 0.97714 0 15.19887 0.44372 14.00041 0.40873 2.51682 0.18053 2.31839 0.16629 60110.972318 0.000512 0.15329 0.01187 1.00000 0 15.80501 0.44747 14.55869 0.41219 2.42282 0.17462 2.23185 0.16085 60110.973241 0.000411 0.19927 0.01548 0.99296 0 15.55339 0.49936 14.26435 0.45798 3.09926 0.21916 2.84161 0.20093 60110.974143 0.000492 0.17410 0.01344 0.98235 0 14.93964 0.44572 13.75687 0.41043 2.60099 0.18520 2.39434 0.17049 60110.975512 0.000877 0.17308 0.01004 0.99010 0 15.09077 0.33801 13.87655 0.31082 2.61199 0.13977 2.40185 0.12853
