/* ** ** 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 54976.037096 0.000515 0.11781 0.00879 0.98876 0 21.11294 0.51174 19.41997 0.47070 2.48733 0.17544 2.28789 0.16138 54976.038074 0.000463 0.12903 0.00982 0.99375 0 21.39275 0.55005 19.33272 0.49706 2.76022 0.19773 2.49742 0.17889 54976.039064 0.000527 0.12000 0.00907 0.99451 0 20.78886 0.50806 18.75259 0.45830 2.49463 0.17849 2.25278 0.16115 54976.103729 0.000463 0.12293 0.00939 0.98750 0 22.18865 0.55385 20.35890 0.50814 2.72770 0.19682 2.50101 0.18044 54976.104657 0.000466 0.12177 0.00939 0.99379 0 21.83486 0.54766 20.18466 0.50627 2.65883 0.19388 2.45933 0.17936 54976.105696 0.000573 0.12643 0.00867 0.98729 0 21.43172 0.49280 19.68767 0.45269 2.70953 0.17503 2.49201 0.16096 54976.170517 0.000952 0.13564 0.01043 0.97872 0 23.33091 0.62017 9.08974 0.24072 3.16471 0.22839 1.23106 0.08856 54976.172204 0.000735 0.11635 0.01078 0.97454 0 22.97541 0.68616 9.19557 0.27459 2.67311 0.23442 1.07182 0.09397 54976.237799 0.000524 0.12565 0.00965 0.99448 0 19.48820 0.49723 17.47236 0.44579 2.44861 0.17729 2.19676 0.15907 54976.239307 0.000984 0.10967 0.00650 0.98713 0 19.65276 0.36275 17.71464 0.32697 2.15535 0.12133 1.94331 0.10940 54976.372466 0.001163 0.13055 0.01051 0.97031 0 20.28040 0.54627 7.14061 0.19211 2.64771 0.20088 0.93351 0.07075 54976.705728 0.000399 0.15462 0.01201 1.00000 0 23.75459 0.67710 18.71325 0.53181 3.67298 0.26535 2.87748 0.20713 54976.706593 0.000466 0.13542 0.01038 0.98137 0 24.23848 0.63763 18.57566 0.48862 3.28242 0.23625 2.51324 0.18091 54976.707707 0.000648 0.13569 0.00901 0.99001 0 23.40528 0.52987 18.00494 0.40757 3.17586 0.19819 2.44429 0.15248 54976.774194 0.001513 0.14992 0.00960 0.96129 0 21.26931 0.48938 7.60973 0.17486 3.18863 0.19053 1.14489 0.06837 54976.839124 0.000341 0.16439 0.01306 1.00000 0 22.14581 0.65182 20.04984 0.59009 3.64046 0.26856 3.29891 0.24336 54976.839821 0.000356 0.16314 0.01273 0.98374 0 21.95137 0.63614 19.98317 0.57910 3.58106 0.25948 3.26140 0.23629 54976.840541 0.000365 0.15701 0.01209 0.98413 0 22.32080 0.62959 20.37472 0.57469 3.50457 0.25116 3.19876 0.22924 54976.841245 0.000339 0.16884 0.01336 1.00000 0 21.74350 0.64810 19.74484 0.58849 3.67106 0.26912 3.33288 0.24430 54976.841979 0.000396 0.17740 0.01273 0.95588 0 21.93908 0.60294 19.80354 0.54422 3.89196 0.25809 3.51333 0.23296 54976.905802 0.000353 0.15463 0.01202 1.00000 0 22.87954 0.64827 20.87697 0.59148 3.53793 0.25609 3.22705 0.23362 54976.906508 0.000353 0.15155 0.01175 0.98361 0 23.47229 0.65349 21.64866 0.60272 3.55714 0.25752 3.28083 0.23752 54976.907237 0.000376 0.13961 0.01083 0.98462 0 23.99656 0.63929 22.13387 0.58967 3.35009 0.24405 3.09008 0.22511 54976.908328 0.000715 0.14523 0.00816 0.99172 0 22.41542 0.44785 20.67902 0.41316 3.25544 0.17097 3.00324 0.15772 54976.973175 0.000365 0.14971 0.01151 0.97619 0 23.39389 0.64234 21.51669 0.59078 3.50222 0.25138 3.22196 0.23124 54976.973881 0.000341 0.16141 0.01249 1.00000 0 22.47131 0.64857 20.80867 0.60059 3.62704 0.26032 3.35848 0.24104 54976.974618 0.000396 0.13581 0.01035 0.98540 0 23.55366 0.61695 21.74357 0.56953 3.19883 0.22901 2.95040 0.21121 54976.975701 0.000686 0.14558 0.00818 0.99156 0 23.62561 0.47016 21.72818 0.43240 3.43953 0.18069 3.16199 0.16611
