/* ** ** 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 57482.285859 0.000486 0.13527 0.01046 0.98810 0 19.61637 0.51894 17.54410 0.46410 2.65358 0.19270 2.36973 0.17208 57482.286829 0.000483 0.12620 0.00973 0.99401 0 21.29274 0.54407 18.89653 0.48282 2.68714 0.19537 2.38288 0.17327 57482.287746 0.000434 0.13549 0.01049 1.00000 0 21.77917 0.58231 19.33516 0.51691 2.95085 0.21434 2.62250 0.19043 57482.288617 0.000437 0.14159 0.01095 0.99338 0 20.78239 0.56389 18.61620 0.50511 2.94257 0.21312 2.63586 0.19090 57482.289537 0.000483 0.12961 0.00984 0.98802 0 20.90986 0.53500 18.64430 0.47701 2.71021 0.19371 2.41833 0.17284 57482.290498 0.000477 0.13377 0.01012 0.99394 0 20.45760 0.53394 18.26750 0.47676 2.73659 0.19430 2.44419 0.17354 57482.291450 0.000475 0.13413 0.01021 0.99390 0 20.50587 0.53869 18.24990 0.47939 2.75050 0.19657 2.44800 0.17496 57482.292370 0.000446 0.14011 0.01077 1.00000 0 20.67906 0.56060 18.41538 0.49917 2.89733 0.20847 2.57923 0.18557 57482.293290 0.000475 0.12520 0.00994 1.00000 0 20.98682 0.54419 18.71694 0.48534 2.62765 0.19726 2.34305 0.17594 57482.294274 0.000509 0.12749 0.00965 0.99432 0 20.00415 0.51422 17.86427 0.45922 2.55035 0.18154 2.27911 0.16223 57482.295223 0.000440 0.15226 0.01167 0.98684 0 19.62949 0.55090 17.55082 0.49258 2.98887 0.21307 2.67352 0.19059 57482.296108 0.000446 0.14404 0.01109 0.99351 0 20.14393 0.55066 18.03094 0.49289 2.90158 0.20876 2.59609 0.18678 57482.297231 0.000677 0.11500 0.00792 0.99145 0 20.50760 0.45076 18.27911 0.40175 2.35834 0.15385 2.10221 0.13712
