/* ** ** 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 56739.050701 0.000298 0.15503 0.01189 0.96117 0 28.34024 0.78236 25.88379 0.71455 4.39365 0.31447 4.01273 0.28721 56739.051291 0.000292 0.16076 0.01263 0.98020 0 26.99556 0.77580 24.65997 0.70868 4.33975 0.31745 3.96414 0.28997 56739.051885 0.000301 0.15297 0.01182 0.99038 0 28.09392 0.78633 25.07470 0.70176 4.29748 0.30953 3.84036 0.27655 56739.052446 0.000260 0.17331 0.01334 0.98889 0 28.99601 0.85790 26.12881 0.77312 5.02529 0.35698 4.53112 0.32185 56739.052993 0.000286 0.15478 0.01208 1.00000 0 28.30950 0.80375 25.70905 0.72992 4.38168 0.31862 3.98134 0.28946 56739.053572 0.000292 0.15340 0.01189 0.99010 0 28.59502 0.80194 25.81591 0.72396 4.38655 0.31697 3.95856 0.28606 56739.054179 0.000315 0.13640 0.01041 0.99083 0 29.67900 0.78383 26.96982 0.71226 4.04827 0.28974 3.67833 0.26327 56739.054801 0.000307 0.15187 0.01164 0.98113 0 27.82433 0.76984 25.42413 0.70343 4.22574 0.30196 3.86122 0.27592 56739.055423 0.000315 0.14341 0.01101 1.00000 0 28.00302 0.76161 25.44877 0.69217 4.01581 0.28845 3.64734 0.26197 56739.056037 0.000298 0.14652 0.01114 1.00000 0 29.07781 0.79608 26.56965 0.72741 4.26037 0.30232 3.89288 0.27624 56739.056616 0.000281 0.15520 0.01225 1.00000 0 28.60215 0.81573 25.94626 0.74001 4.43905 0.32664 4.02831 0.29647 56739.057188 0.000292 0.16363 0.01257 0.99010 0 27.13682 0.78487 24.38250 0.70520 4.44036 0.31593 3.98964 0.28383 56739.057756 0.000275 0.16747 0.01285 0.98947 0 28.21433 0.82462 25.45185 0.74374 4.72505 0.33529 4.26560 0.30269 56739.058308 0.000278 0.15197 0.01178 1.00000 0 29.70102 0.83403 27.13562 0.76199 4.51363 0.32617 4.12350 0.29798 56739.058899 0.000312 0.14553 0.01127 0.98148 0 28.10196 0.76728 25.52091 0.69681 4.08972 0.29629 3.71560 0.26920 56739.059506 0.000295 0.14232 0.01111 1.00000 0 29.58574 0.80738 27.03403 0.73774 4.21074 0.30801 3.84754 0.28144 56739.060088 0.000286 0.16112 0.01243 0.98990 0 28.01938 0.80330 25.28589 0.72488 4.51461 0.32336 4.07718 0.29209 56739.060701 0.000327 0.13659 0.01065 0.98230 0 28.58444 0.75939 25.76155 0.68436 3.90422 0.28635 3.51753 0.25799 56739.061413 0.000385 0.14636 0.01011 1.00000 0 28.20812 0.69570 25.48853 0.62862 4.12860 0.26652 3.73175 0.24082
