/* ** ** 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 59172.144433 0.000370 0.15427 0.01172 0.96875 0 22.98631 0.63360 21.06633 0.58061 3.54611 0.25109 3.24914 0.23007 59172.145147 0.000344 0.16076 0.01250 0.98319 0 23.13089 0.66607 21.11237 0.60792 3.71853 0.26846 3.39787 0.24525 59172.145807 0.000315 0.16770 0.01302 1.00000 0 24.18053 0.71700 21.84708 0.64784 4.05512 0.29089 3.66359 0.26275 59172.146444 0.000321 0.16246 0.01259 0.99099 0 24.99162 0.72311 22.23298 0.64329 4.06023 0.29194 3.61208 0.25972 59172.147086 0.000321 0.16191 0.01247 0.99099 0 24.94750 0.71828 22.39285 0.64468 4.03925 0.28863 3.62826 0.25921 59172.147725 0.000318 0.17202 0.01325 0.99091 0 23.72328 0.70852 21.39138 0.63867 4.08077 0.28968 3.67789 0.26108 59172.148365 0.000321 0.16310 0.01276 0.99099 0 24.15628 0.70722 21.93754 0.64214 3.93984 0.28585 3.57768 0.25959 59172.149013 0.000327 0.16693 0.01315 0.99115 0 23.24461 0.68589 20.95553 0.61835 3.88021 0.28332 3.49789 0.25545 59172.149664 0.000324 0.17168 0.01329 0.99107 0 23.21230 0.69101 20.95782 0.62385 3.98508 0.28474 3.59558 0.25688 59172.150338 0.000350 0.14439 0.01134 0.99174 0 24.90199 0.68859 22.51713 0.62258 3.59551 0.26435 3.24986 0.23888 59172.150986 0.000298 0.17371 0.01341 0.99029 0 25.03914 0.74437 22.61282 0.67224 4.34957 0.30999 3.93247 0.28023 59172.151626 0.000341 0.15392 0.01211 1.00000 0 23.80814 0.67706 21.56678 0.61333 3.66452 0.26875 3.32192 0.24352 59172.152306 0.000339 0.15368 0.01189 0.99145 0 24.37344 0.68313 22.18829 0.62185 3.74578 0.27015 3.40797 0.24568 59172.152942 0.000298 0.17623 0.01348 0.98058 0 24.73709 0.73309 22.62373 0.67047 4.35931 0.30748 3.98684 0.28121 59172.153556 0.000315 0.16134 0.01268 1.00000 0 24.78116 0.72194 22.28815 0.64925 3.99810 0.29195 3.59416 0.26248 59172.154195 0.000324 0.16332 0.01279 1.00000 0 23.79148 0.69892 21.53737 0.63261 3.88552 0.28195 3.51379 0.25495 59172.154864 0.000344 0.15363 0.01169 0.99160 0 24.39481 0.68542 22.11215 0.62133 3.74783 0.26503 3.39548 0.24010 59172.155547 0.000339 0.16535 0.01276 0.99145 0 22.77138 0.66459 20.81244 0.60741 3.76526 0.26900 3.44060 0.24581 59172.156394 0.000509 0.16634 0.01023 0.99432 0 23.91274 0.55621 21.55971 0.50143 3.97757 0.22652 3.58693 0.20426
