/* ** ** 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 57819.060988 0.000310 0.18047 0.01426 0.99065 0 22.75735 0.69064 20.50594 0.62228 4.10691 0.29963 3.70204 0.27012 57819.061547 0.000249 0.23091 0.01842 0.98837 0 22.23164 0.76679 20.15220 0.69507 5.13359 0.36921 4.65341 0.33467 57819.062050 0.000255 0.23640 0.01889 0.98864 0 21.17762 0.73691 19.23298 0.66924 5.00637 0.36006 4.54644 0.32698 57819.062580 0.000275 0.21928 0.01774 0.98947 0 20.91636 0.70920 18.86977 0.63977 4.58655 0.33694 4.13969 0.30416 57819.063106 0.000252 0.23816 0.01885 0.98851 0 21.52001 0.75168 19.50044 0.68113 5.12514 0.36397 4.64401 0.32977 57819.063604 0.000246 0.23348 0.01856 0.98824 0 22.41873 0.77434 20.23850 0.69903 5.23433 0.37484 4.72407 0.33831 57819.064110 0.000260 0.24022 0.01938 1.00000 0 20.03027 0.70807 18.17681 0.64255 4.81165 0.34902 4.36641 0.31672 57819.064669 0.000298 0.20918 0.01650 0.99029 0 20.61477 0.67529 18.60750 0.60953 4.31211 0.30940 3.89748 0.27958 57819.065282 0.000315 0.18687 0.01487 1.00000 0 21.29101 0.66440 19.33595 0.60339 3.97875 0.29123 3.61339 0.26449 57819.065864 0.000266 0.22118 0.01735 1.00000 0 21.72668 0.73174 19.72608 0.66437 4.80546 0.34038 4.36292 0.30903 57819.066390 0.000260 0.22237 0.01772 1.00000 0 21.85845 0.74026 19.83620 0.67178 4.86062 0.35073 4.41092 0.31828 57819.066934 0.000284 0.21138 0.01691 0.98980 0 21.03782 0.69604 19.10318 0.63203 4.44692 0.32395 4.03809 0.29416 57819.067530 0.000312 0.18368 0.01430 0.99074 0 22.38768 0.68561 20.32998 0.62259 4.11208 0.29422 3.73408 0.26718 57819.068118 0.000275 0.22893 0.01809 0.98947 0 20.47843 0.70421 18.59274 0.63936 4.68819 0.33347 4.25646 0.30277 57819.068650 0.000258 0.22754 0.01792 1.00000 0 21.91240 0.74350 19.89223 0.67496 4.98584 0.35434 4.52620 0.32168 57819.069183 0.000275 0.21474 0.01682 0.98947 0 21.78342 0.72095 19.78619 0.65485 4.67766 0.33216 4.24878 0.30171 57819.069715 0.000258 0.23348 0.01843 0.97753 0 21.70118 0.74177 19.69737 0.67328 5.06678 0.36040 4.59893 0.32713 57819.070227 0.000255 0.24351 0.01934 1.00000 0 20.66940 0.73487 18.63984 0.66274 5.03316 0.35741 4.53847 0.32228 57819.070985 0.000503 0.20900 0.01207 1.00000 0 22.29060 0.53714 20.24184 0.48777 4.65872 0.24442 4.23050 0.22195
