/* ** ** 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 55907.739513 0.000524 0.12728 0.01924 0.99448 0 5.04055 0.25742 4.35654 0.22248 0.64155 0.09128 0.55353 0.07875 55907.740658 0.000622 0.11512 0.01711 0.96744 0 4.93101 0.23411 4.24785 0.20165 0.56766 0.07997 0.48865 0.06883 55907.741958 0.000677 0.08836 0.01377 0.98718 0 5.17143 0.23048 4.47027 0.19923 0.45696 0.06826 0.39434 0.05891 55907.743144 0.000509 0.13764 0.02075 0.97159 0 4.91820 0.25713 4.25791 0.22261 0.67695 0.09574 0.58577 0.08284 55907.744194 0.000541 0.12158 0.01831 0.97326 0 5.20929 0.25694 4.50509 0.22220 0.63332 0.09011 0.54745 0.07789 55907.745288 0.000553 0.12580 0.01899 0.98429 0 4.86074 0.24550 4.21288 0.21277 0.61148 0.08700 0.52998 0.07540 55907.746376 0.000535 0.12332 0.01880 0.96757 0 5.15249 0.25791 4.46570 0.22353 0.63540 0.09150 0.55070 0.07930 55907.747513 0.000602 0.12102 0.01823 0.98077 0 4.65582 0.23087 4.03567 0.20012 0.56347 0.08017 0.48841 0.06949 55907.748433 0.000318 0.09247 0.02163 0.98182 0 4.62878 0.31813 4.01208 0.27575 0.42801 0.09571 0.37099 0.08296 55907.749226 0.000475 0.14945 0.02279 0.96341 0 4.91825 0.26980 4.20865 0.23087 0.73505 0.10458 0.63061 0.08972 55907.750305 0.000605 0.11467 0.01722 0.97608 0 4.92745 0.23732 4.25662 0.20501 0.56504 0.08039 0.48841 0.06949 55907.751226 0.000315 0.09089 0.02130 0.97248 0 4.91226 0.32818 4.25664 0.28438 0.44646 0.10028 0.38687 0.08690 55907.752053 0.000512 0.15408 0.02341 0.96045 0 4.41192 0.24499 3.82408 0.21235 0.67981 0.09614 0.58922 0.08333 55907.753077 0.000512 0.12572 0.01897 0.96610 0 5.36905 0.26936 4.63523 0.23253 0.67498 0.09604 0.58267 0.08290 55907.754139 0.000550 0.12284 0.01833 0.97368 0 5.18470 0.25591 4.47801 0.22103 0.63687 0.08971 0.54940 0.07739 55907.755169 0.000480 0.14824 0.02273 0.98193 0 4.73252 0.26033 4.10149 0.22561 0.70157 0.10042 0.60801 0.08703 55907.756283 0.000634 0.12533 0.01683 0.98174 0 5.38205 0.24160 4.66411 0.20937 0.67454 0.08539 0.58456 0.07400
