/* ** ** 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 57790.150514 0.000263 0.22318 0.01783 0.98901 0 21.58329 0.73339 19.62718 0.66687 4.81703 0.34836 4.38038 0.31682 57790.151052 0.000275 0.21326 0.01678 0.96842 0 22.38440 0.73554 20.25399 0.66545 4.77360 0.34141 4.32012 0.30894 57790.151610 0.000284 0.20778 0.01656 1.00000 0 21.19943 0.69843 19.38003 0.63848 4.40490 0.31956 4.02683 0.29213 57790.152183 0.000289 0.20577 0.01594 0.98000 0 21.84749 0.70007 19.96809 0.63985 4.49567 0.31710 4.10888 0.28982 57790.152788 0.000315 0.18320 0.01455 0.99083 0 21.83397 0.67467 19.87295 0.61408 3.99996 0.29267 3.64274 0.26656 57790.153424 0.000321 0.18688 0.01469 1.00000 0 20.94986 0.65278 19.09659 0.59500 3.91502 0.28244 3.56971 0.25751 57790.154041 0.000295 0.20988 0.01649 1.00000 0 20.64345 0.67990 18.67983 0.61521 4.33272 0.30910 3.91621 0.27934 57790.154637 0.000301 0.20357 0.01641 1.00000 0 20.31316 0.66838 18.51518 0.60915 4.13507 0.30433 3.76738 0.27725 57790.155247 0.000310 0.19394 0.01519 0.98131 0 21.49829 0.67627 19.52601 0.61425 4.16934 0.29909 3.78901 0.27179 57790.155896 0.000339 0.17459 0.01358 0.96581 0 22.21003 0.65566 20.20874 0.59659 3.87774 0.27898 3.52425 0.25357 57790.156523 0.000289 0.20232 0.01597 1.00000 0 21.66056 0.70176 19.70874 0.63852 4.38234 0.31533 3.98241 0.28654 57790.157093 0.000281 0.20293 0.01608 1.00000 0 21.93793 0.71113 20.01220 0.64867 4.45178 0.32197 4.06427 0.29395 57790.157675 0.000301 0.19832 0.01548 1.00000 0 21.28717 0.68209 19.46439 0.62368 4.22168 0.30037 3.86017 0.27465 57790.158268 0.000292 0.20210 0.01592 1.00000 0 21.44200 0.69746 19.46735 0.63327 4.33347 0.31086 3.93907 0.28256 57790.158856 0.000295 0.19010 0.01547 1.00000 0 21.69780 0.69357 19.83417 0.63400 4.12465 0.30871 3.77043 0.28220 57790.159434 0.000284 0.21846 0.01767 1.00000 0 20.10882 0.68322 18.26884 0.62075 4.39303 0.32238 3.99401 0.29305 57790.160007 0.000289 0.20177 0.01605 1.00000 0 21.40711 0.69822 19.56281 0.63807 4.31930 0.31336 3.94629 0.28629 57790.160583 0.000286 0.21312 0.01680 1.00000 0 21.17422 0.70038 18.94532 0.62668 4.51254 0.32288 4.03888 0.28898 57790.161338 0.000469 0.22556 0.01340 0.98765 0 21.96447 0.55976 19.58208 0.49904 4.95437 0.26590 4.41721 0.23710
