/* ** ** 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 56333.127712 0.000518 0.14205 0.01107 0.97207 0 18.47226 0.49700 15.84443 0.42628 2.62402 0.19185 2.25005 0.16452 56333.128734 0.000503 0.14975 0.01173 0.99425 0 17.97252 0.50202 15.19922 0.42454 2.69143 0.19703 2.27563 0.16661 56333.129712 0.000475 0.15264 0.01179 0.99390 0 18.69327 0.52632 15.96384 0.44946 2.85330 0.20531 2.43666 0.17533 56333.130632 0.000446 0.14896 0.01194 1.00000 0 19.88757 0.56561 16.83178 0.47864 2.96248 0.22199 2.50771 0.18785 56333.131581 0.000503 0.14391 0.01116 1.00000 0 18.49801 0.51108 15.79212 0.43633 2.66207 0.19284 2.27209 0.16458 56333.132599 0.000515 0.13205 0.01046 1.00000 0 19.29786 0.51379 16.41119 0.43692 2.54829 0.19010 2.16862 0.16180 56333.133566 0.000451 0.15024 0.01160 1.00000 0 19.91943 0.55627 16.95026 0.47334 2.99263 0.21532 2.54600 0.18320 56333.134515 0.000498 0.13275 0.01038 0.98837 0 20.31188 0.53629 17.26820 0.45588 2.69639 0.19845 2.29222 0.16873 56333.135516 0.000503 0.14652 0.01165 0.98851 0 18.06847 0.50523 15.39642 0.43050 2.64738 0.19700 2.25592 0.16785 56333.136439 0.000420 0.17132 0.01320 0.98621 0 19.09966 0.56376 16.27870 0.48049 3.27216 0.23292 2.78906 0.19854 56333.137365 0.000506 0.13594 0.01045 0.98286 0 19.81870 0.52402 16.90040 0.44686 2.69420 0.19437 2.29751 0.16575 56333.138369 0.000498 0.17676 0.01282 0.98256 0 18.51689 0.51586 15.53331 0.43274 3.27298 0.21919 2.74337 0.18371
