/* ** ** 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 59323.047506 0.000275 0.22238 0.01781 1.00000 0 22.11181 0.75554 18.71412 0.63936 4.91734 0.35628 4.16104 0.30148 59323.048102 0.000321 0.18460 0.01503 1.00000 0 22.35191 0.70196 19.05938 0.59853 4.12616 0.31004 3.51722 0.26421 59323.048690 0.000266 0.22313 0.01771 0.98913 0 22.72754 0.77459 19.55520 0.66648 5.07113 0.36342 4.36243 0.31265 59323.049260 0.000304 0.18277 0.01471 1.00000 0 23.46861 0.72977 20.32153 0.63191 4.28930 0.31841 3.71362 0.27568 59323.049870 0.000307 0.18467 0.01451 0.98113 0 23.93748 0.73749 20.69046 0.63744 4.42064 0.31945 3.82021 0.27606 59323.050435 0.000258 0.23392 0.01896 0.98876 0 22.21707 0.78366 19.11548 0.67408 5.19712 0.37914 4.47108 0.32613 59323.050976 0.000284 0.18909 0.01490 1.00000 0 24.72586 0.77649 21.44024 0.67331 4.67545 0.33786 4.05410 0.29296 59323.051543 0.000284 0.19000 0.01504 1.00000 0 24.37349 0.76803 21.12217 0.66559 4.63084 0.33639 4.01322 0.29153 59323.052124 0.000298 0.18298 0.01448 0.99029 0 24.45086 0.75174 21.08844 0.64832 4.47410 0.32629 3.85741 0.28137 59323.052726 0.000304 0.18293 0.01433 1.00000 0 23.90146 0.73911 20.67443 0.63932 4.37230 0.31466 3.78230 0.27220 59323.053331 0.000301 0.19564 0.01535 0.99038 0 22.80124 0.72738 19.71127 0.62881 4.46075 0.31969 3.85418 0.27622 59323.053927 0.000295 0.20620 0.01631 0.97059 0 22.80663 0.73709 19.66840 0.63563 4.70283 0.33941 4.05524 0.29271 59323.054538 0.000315 0.17924 0.01434 0.97248 0 23.93781 0.72996 20.52381 0.62581 4.29066 0.31735 3.67707 0.27186 59323.055206 0.000353 0.17411 0.01330 0.99147 0 23.03188 0.67366 19.91850 0.58260 4.01005 0.28290 3.46811 0.24467
