/* ** ** 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 59170.153175 0.000295 0.16993 0.01310 1.00000 0 25.25805 0.74194 23.16028 0.68028 4.29214 0.30591 3.93206 0.28026 59170.153768 0.000298 0.17109 0.01345 1.00000 0 24.54613 0.74213 22.32379 0.67497 4.19952 0.30473 3.82000 0.27728 59170.154364 0.000298 0.17366 0.01334 1.00000 0 24.66127 0.73412 22.52981 0.67063 4.28278 0.30332 3.91138 0.27699 59170.154940 0.000278 0.17722 0.01394 1.00000 0 25.33084 0.76930 23.15023 0.70304 4.48906 0.32580 4.09855 0.29750 59170.155533 0.000315 0.15532 0.01204 1.00000 0 25.38704 0.72332 23.34647 0.66518 3.94320 0.28435 3.62626 0.26149 59170.156155 0.000307 0.16543 0.01281 1.00000 0 24.62197 0.72391 22.64364 0.66575 4.07316 0.29180 3.74588 0.26836 59170.156743 0.000281 0.19049 0.01529 0.98969 0 23.18420 0.74686 21.31934 0.68678 4.41624 0.32480 4.06101 0.29868 59170.157316 0.000292 0.16936 0.01321 0.99010 0 25.38003 0.75440 23.33913 0.69374 4.29826 0.30995 3.95262 0.28503 59170.157868 0.000260 0.18325 0.01421 1.00000 0 26.29910 0.81121 24.18429 0.74598 4.81938 0.34301 4.43184 0.31543 59170.158430 0.000301 0.17478 0.01348 0.98077 0 24.33020 0.72425 22.37334 0.66600 4.25247 0.30266 3.91044 0.27832 59170.159026 0.000295 0.16875 0.01316 1.00000 0 24.97060 0.74303 22.96321 0.68330 4.21388 0.30387 3.87512 0.27944 59170.159659 0.000339 0.14836 0.01133 1.00000 0 25.09024 0.69223 22.95038 0.63320 3.72245 0.26497 3.40911 0.24264 59170.160310 0.000312 0.16488 0.01296 1.00000 0 24.04732 0.70839 22.10618 0.65120 3.96501 0.28897 3.64502 0.26562 59170.160930 0.000307 0.16549 0.01288 0.99057 0 24.73536 0.72251 22.74659 0.66442 4.09352 0.29519 3.76440 0.27145 59170.161563 0.000327 0.15353 0.01178 0.99115 0 25.23797 0.70753 23.20846 0.65063 3.87469 0.27687 3.56310 0.25461 59170.162183 0.000292 0.18128 0.01351 1.00000 0 25.72466 0.75294 23.65549 0.69237 4.66346 0.31966 4.28835 0.29394
