/* ** ** 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 54978.913739 0.000318 0.16063 0.01245 0.99091 0 25.68445 0.73944 22.71204 0.65387 4.12563 0.29681 3.64387 0.26219 54978.914388 0.000330 0.14480 0.01130 1.00000 0 26.87450 0.74236 23.84032 0.65851 3.89147 0.28395 3.45196 0.25171 54978.915050 0.000333 0.14336 0.01105 0.99130 0 26.88992 0.72996 24.17981 0.65639 3.85494 0.27810 3.46648 0.25007 54978.915693 0.000310 0.15715 0.01209 1.00000 0 26.56815 0.75543 23.73677 0.67489 4.17531 0.29841 3.72908 0.26654 54978.916277 0.000275 0.18518 0.01425 1.00000 0 25.52811 0.78711 22.89190 0.70583 4.72717 0.33343 4.23864 0.29897 54978.916830 0.000278 0.17379 0.01355 1.00000 0 26.49526 0.79466 23.80527 0.71398 4.60467 0.33131 4.13731 0.29769 54978.917397 0.000289 0.15141 0.01197 0.99000 0 29.29797 0.82565 25.96676 0.73176 4.43593 0.32770 3.93802 0.29103 54978.917952 0.000266 0.19906 0.01552 0.98913 0 24.65484 0.79249 22.12275 0.71109 4.90787 0.34848 4.40484 0.31276 54978.918482 0.000263 0.18706 0.01471 1.00000 0 25.80545 0.80638 23.21542 0.72545 4.82710 0.34823 4.34262 0.31328 54978.919032 0.000286 0.17198 0.01346 1.00000 0 25.93650 0.77925 23.33958 0.70122 4.46063 0.32226 4.01369 0.28997 54978.919625 0.000307 0.15508 0.01202 1.00000 0 26.72660 0.75867 24.03915 0.68238 4.14486 0.29901 3.72810 0.26894 54978.920261 0.000330 0.15512 0.01212 0.99123 0 25.17269 0.71744 22.57155 0.64334 3.90470 0.28401 3.50023 0.25456 54978.920910 0.000318 0.16250 0.01309 0.96364 0 25.16988 0.73360 22.32908 0.65067 4.09011 0.30728 3.62454 0.27225 54978.921497 0.000269 0.18011 0.01422 0.98925 0 26.69146 0.81734 23.85439 0.73043 4.80738 0.34974 4.29920 0.31266 54978.922053 0.000286 0.17023 0.01332 1.00000 0 26.24855 0.77840 23.45784 0.69564 4.46824 0.32359 3.99346 0.28926 54978.922617 0.000278 0.17848 0.01409 1.00000 0 25.79441 0.78960 23.07818 0.70647 4.60389 0.33494 4.12007 0.29964 54978.923204 0.000310 0.16557 0.01256 0.99065 0 25.90429 0.74719 23.17471 0.66837 4.28887 0.30103 3.83658 0.26927 54978.923847 0.000333 0.14014 0.01072 1.00000 0 27.64100 0.74255 24.68943 0.66318 3.87374 0.27756 3.45224 0.24739 54978.924581 0.000402 0.15701 0.01063 0.99281 0 27.29608 0.67611 24.06018 0.59596 4.28569 0.27006 3.78070 0.23817
