/* ** ** 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 57550.411400 0.000252 0.17470 0.01356 0.98851 0 29.08878 0.86558 26.37605 0.78478 5.08180 0.36435 4.61124 0.33058 57550.411909 0.000258 0.16761 0.01320 1.00000 0 28.94678 0.85598 26.39503 0.78052 4.85170 0.35406 4.42403 0.32285 57550.412386 0.000220 0.20572 0.01603 1.00000 0 28.18991 0.91518 25.64742 0.83262 5.79917 0.41091 5.28031 0.37415 57550.412858 0.000252 0.16890 0.01310 1.00000 0 30.11382 0.89091 26.98557 0.79833 5.08618 0.36467 4.55823 0.32678 57550.413321 0.000211 0.22550 0.01784 1.00000 0 26.49125 0.90405 24.17523 0.82502 5.97369 0.42629 5.45114 0.38900 57550.413795 0.000263 0.16584 0.01279 1.00000 0 29.05825 0.85127 26.36391 0.77234 4.81903 0.34389 4.37289 0.31206 57550.414319 0.000260 0.18205 0.01432 0.97778 0 27.21568 0.83105 24.59642 0.75108 4.95449 0.35922 4.48260 0.32499 57550.414837 0.000258 0.18703 0.01470 1.00000 0 26.28439 0.82050 23.79873 0.74290 4.91589 0.35474 4.44760 0.32097 57550.415306 0.000211 0.22147 0.01741 0.97260 0 27.99795 0.93406 25.44369 0.84876 6.20075 0.44137 5.63291 0.40096 57550.415737 0.000220 0.21871 0.01712 1.00000 0 26.73532 0.89183 24.31186 0.81092 5.84730 0.41412 5.31504 0.37643 57550.416191 0.000234 0.18720 0.01450 0.98765 0 29.39670 0.90616 26.72274 0.82374 5.50292 0.39091 4.99125 0.35455 57550.416680 0.000255 0.18159 0.01413 0.97727 0 28.27776 0.85488 25.38074 0.76727 5.13491 0.36817 4.61124 0.33058 57550.417192 0.000258 0.17763 0.01383 1.00000 0 28.20085 0.85588 25.10465 0.76186 5.00926 0.35914 4.45580 0.31944 57550.417693 0.000243 0.18385 0.01435 1.00000 0 28.57230 0.87960 25.69438 0.79090 5.25304 0.37665 4.72103 0.33845 57550.418176 0.000240 0.20109 0.01575 1.00000 0 26.33900 0.85100 23.84661 0.77043 5.29647 0.37795 4.79438 0.34214 57550.418674 0.000258 0.17132 0.01343 1.00000 0 28.66326 0.85564 25.88696 0.77269 4.91048 0.35596 4.43224 0.32134 57550.419183 0.000252 0.17231 0.01332 0.98851 0 29.86205 0.88501 26.86170 0.79613 5.14558 0.36725 4.62713 0.33020 57550.419658 0.000223 0.19901 0.01568 0.98701 0 28.96941 0.92656 26.15223 0.83650 5.76527 0.41524 5.19999 0.37451 57550.420141 0.000260 0.17897 0.01381 1.00000 0 27.73180 0.83702 24.96689 0.75353 4.96325 0.35243 4.46600 0.31709 57550.420642 0.000240 0.19292 0.01519 0.98795 0 27.62047 0.86913 25.01268 0.78696 5.32864 0.38453 4.82727 0.34837 57550.421102 0.000220 0.21647 0.01702 1.00000 0 26.85501 0.89536 24.30338 0.81027 5.81340 0.41384 5.26232 0.37458 57550.421605 0.000284 0.16353 0.01270 1.00000 0 27.27536 0.79281 24.65671 0.71669 4.46027 0.32125 4.03265 0.29044 57550.422265 0.000376 0.17489 0.01143 1.00000 0 27.60460 0.69530 24.70982 0.62236 4.82766 0.29119 4.32394 0.26076
