/* ** ** 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 58443.619146 0.000347 0.16651 0.01301 1.00000 0 21.46765 0.63286 19.78709 0.58329 3.57451 0.25873 3.29596 0.23856 58443.619791 0.000298 0.17636 0.01396 1.00000 0 23.55389 0.71559 21.54286 0.65447 4.15397 0.30356 3.80314 0.27779 58443.620471 0.000382 0.15101 0.01157 0.98485 0 21.94636 0.60687 20.32991 0.56217 3.31404 0.23678 3.06994 0.21934 58443.621189 0.000336 0.16260 0.01272 1.00000 0 22.52388 0.65881 20.86241 0.61021 3.66248 0.26578 3.39234 0.24618 58443.621823 0.000298 0.18209 0.01419 1.00000 0 23.11350 0.70493 21.28122 0.64903 4.20879 0.30186 3.87677 0.27807 58443.622410 0.000289 0.19646 0.01540 1.00000 0 21.82236 0.69514 20.21257 0.64386 4.28725 0.30710 3.97089 0.28444 58443.623026 0.000327 0.18455 0.01468 1.00000 0 20.50851 0.63875 18.99653 0.59166 3.78490 0.27709 3.50583 0.25666 58443.623654 0.000301 0.19381 0.01517 0.99038 0 21.61040 0.68175 19.90066 0.62777 4.18831 0.30009 3.85524 0.27616 58443.624259 0.000304 0.18227 0.01420 0.99048 0 22.61466 0.69319 20.94832 0.64211 4.12189 0.29526 3.81817 0.27350 58443.624881 0.000318 0.16728 0.01328 1.00000 0 22.87595 0.68330 21.19069 0.63296 3.82674 0.28135 3.54486 0.26062 58443.625544 0.000344 0.16271 0.01250 0.98319 0 22.61936 0.65263 20.95254 0.60454 3.68041 0.26193 3.40922 0.24263 58443.626177 0.000289 0.18756 0.01479 1.00000 0 22.76356 0.71086 21.08704 0.65851 4.26961 0.30903 3.95515 0.28627 58443.626768 0.000301 0.17548 0.01380 1.00000 0 23.27749 0.70706 21.56223 0.65496 4.08475 0.29642 3.78377 0.27458 58443.627378 0.000310 0.18511 0.01450 1.00000 0 21.65500 0.67154 20.05966 0.62206 4.00845 0.28825 3.71312 0.26702 58443.627986 0.000298 0.19074 0.01510 0.99029 0 21.83325 0.68978 20.22623 0.63901 4.16451 0.30221 3.85796 0.27996 58443.628588 0.000304 0.17401 0.01360 1.00000 0 23.39339 0.70580 21.64384 0.65294 4.07067 0.29348 3.76477 0.27143 58443.629175 0.000284 0.19938 0.01582 0.97959 0 22.32511 0.71716 20.58727 0.66140 4.45126 0.32299 4.09908 0.29746 58443.629748 0.000289 0.18749 0.01455 0.99000 0 23.19791 0.71694 21.48959 0.66414 4.34935 0.30954 4.02907 0.28675 58443.630634 0.000596 0.17869 0.01000 1.00000 0 22.71508 0.49525 21.04198 0.45877 4.05905 0.20912 3.76007 0.19372
