/* ** ** 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 57527.613923 0.000367 0.18451 0.01437 1.00000 0 18.70990 0.57264 17.07930 0.52266 3.45211 0.24718 3.14728 0.22533 57527.614655 0.000365 0.18012 0.01423 1.00000 0 18.86610 0.57853 17.30726 0.53070 3.39821 0.24741 3.11417 0.22677 57527.615382 0.000362 0.17964 0.01404 1.00000 0 19.11390 0.58274 17.62176 0.53725 3.43363 0.24710 3.16558 0.22781 57527.616085 0.000341 0.19091 0.01513 1.00000 0 18.98981 0.60258 17.50714 0.55554 3.62531 0.26329 3.34227 0.24273 57527.616779 0.000353 0.19437 0.01502 1.00000 0 18.52652 0.58312 17.07961 0.53758 3.60107 0.25421 3.31983 0.23435 57527.617456 0.000324 0.21958 0.01752 0.98214 0 17.69538 0.59395 16.31371 0.54758 3.88559 0.28127 3.58219 0.25931 57527.618157 0.000376 0.18197 0.01405 0.98462 0 18.67492 0.56884 17.21682 0.52442 3.39824 0.24109 3.13292 0.22227 57527.618863 0.000330 0.22028 0.01725 0.97368 0 17.78913 0.59058 16.40035 0.54447 3.91866 0.27801 3.61273 0.25631 57527.619676 0.000483 0.18812 0.01249 0.98839 0 19.29471 0.51072 17.78674 0.47081 3.62966 0.22098 3.34607 0.20372 57527.685110 0.000420 0.17740 0.01376 0.98621 0 17.22348 0.52119 15.73844 0.47624 3.05541 0.21825 2.79153 0.19936 57527.685960 0.000431 0.16358 0.01279 1.00000 0 17.65648 0.51734 16.15340 0.47329 2.88827 0.20939 2.64232 0.19157 57527.686814 0.000422 0.18316 0.01419 0.97260 0 16.76465 0.51266 15.34158 0.46906 3.07062 0.21848 2.80934 0.19989 57527.687694 0.000457 0.20209 0.01462 1.00000 0 16.46498 0.48379 15.12365 0.44438 3.32744 0.22001 3.05636 0.20209
