/* ** ** 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 56064.154714 0.000350 0.15548 0.01192 0.99174 0 23.45683 0.65699 21.33690 0.59757 3.64702 0.26030 3.31589 0.23665 56064.155394 0.000330 0.14772 0.01125 0.99123 0 26.16213 0.71557 23.92341 0.65433 3.86480 0.27455 3.53351 0.25102 56064.156094 0.000370 0.14184 0.01096 0.99219 0 24.06309 0.65195 21.87159 0.59253 3.41315 0.24707 3.10053 0.22440 56064.156800 0.000336 0.15495 0.01177 0.98276 0 25.27709 0.70188 22.83338 0.63404 3.91663 0.27686 3.53766 0.25005 56064.157526 0.000391 0.13583 0.01033 0.98519 0 24.34347 0.63717 22.05231 0.57712 3.30664 0.23598 2.99178 0.21352 56064.158308 0.000391 0.13144 0.01000 0.99259 0 24.95565 0.64803 22.60149 0.58686 3.28010 0.23461 2.97411 0.21271 56064.159074 0.000376 0.13423 0.01020 0.99231 0 25.44921 0.66498 22.96433 0.60000 3.41602 0.24385 3.08455 0.22014 56064.159806 0.000356 0.14686 0.01133 0.99187 0 24.46068 0.67220 22.03122 0.60537 3.59217 0.25885 3.23891 0.23332 56064.160489 0.000327 0.14338 0.01105 1.00000 0 27.31943 0.74696 24.37710 0.66650 3.91708 0.28220 3.49688 0.25191 56064.161192 0.000376 0.13598 0.01052 0.98462 0 24.87314 0.65698 22.54883 0.59554 3.38213 0.24589 3.06552 0.22291 56064.161965 0.000396 0.12771 0.00981 1.00000 0 24.84085 0.63955 22.49301 0.57911 3.17255 0.22963 2.87421 0.20802 56064.162700 0.000339 0.15149 0.01163 1.00000 0 25.04355 0.69760 22.49838 0.62667 3.79386 0.27135 3.40624 0.24361 56064.163392 0.000353 0.14538 0.01110 0.98361 0 25.29674 0.68591 22.80933 0.61841 3.67759 0.26252 3.31589 0.23665 56064.164155 0.000411 0.12476 0.00948 0.98592 0 25.21719 0.63738 22.68175 0.57324 3.14606 0.22555 2.83234 0.20309 56064.165249 0.000683 0.13795 0.00763 0.99153 0 25.99792 0.49683 23.55013 0.45004 3.58634 0.18612 3.24624 0.16849
