/* ** ** 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 58854.190821 0.000391 0.15005 0.01154 0.97778 0 22.25891 0.61284 20.01414 0.55106 3.33995 0.23985 3.00112 0.21554 58854.191625 0.000414 0.13887 0.01085 0.98601 0 21.85901 0.58630 19.92355 0.53436 3.03555 0.22266 2.76682 0.20291 58854.192462 0.000422 0.13824 0.01066 0.97945 0 21.97886 0.58326 20.11549 0.53382 3.03828 0.21991 2.78069 0.20126 58854.193286 0.000402 0.14399 0.01133 0.99281 0 21.37117 0.58594 19.55755 0.53621 3.07725 0.22687 2.81606 0.20761 58854.194102 0.000414 0.13500 0.01038 1.00000 0 22.33591 0.58997 20.44215 0.53995 3.01539 0.21770 2.75973 0.19924 58854.194901 0.000385 0.14883 0.01148 0.99248 0 22.19952 0.61357 20.31723 0.56154 3.30396 0.23791 3.02383 0.21774 58854.195670 0.000385 0.15434 0.01190 0.98496 0 21.40773 0.60066 19.59275 0.54974 3.30416 0.23730 3.02403 0.21719 58854.196440 0.000385 0.15636 0.01201 0.99248 0 21.05161 0.59512 19.26651 0.54466 3.29165 0.23518 3.01253 0.21524 58854.197233 0.000408 0.14501 0.01114 0.98582 0 21.47461 0.58443 19.65364 0.53487 3.11404 0.22365 2.84998 0.20469 58854.198061 0.000420 0.14137 0.01106 0.99310 0 20.94015 0.57051 19.16433 0.52213 2.96022 0.21709 2.70918 0.19868 58854.198917 0.000437 0.14578 0.01125 0.99338 0 19.97005 0.54449 18.27662 0.49832 2.91114 0.21016 2.66428 0.19234 58854.199779 0.000425 0.13573 0.01044 0.99320 0 21.88694 0.57964 19.95729 0.52849 2.97072 0.21445 2.70302 0.19515 58854.200595 0.000391 0.15070 0.01161 0.99259 0 21.43594 0.59796 19.61787 0.54724 3.23030 0.23200 2.95633 0.21232 58854.201521 0.000535 0.12814 0.00913 0.98919 0 21.53822 0.51169 19.71152 0.46829 2.75999 0.18529 2.52591 0.16958
