/* ** ** 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 57841.043561 0.000318 0.19037 0.01509 0.99091 0 21.67395 0.68286 19.11121 0.60196 4.12602 0.30003 3.62940 0.26385 57841.044183 0.000304 0.20416 0.01632 1.00000 0 20.52764 0.67265 18.36193 0.60168 4.19101 0.30548 3.74859 0.27324 57841.044803 0.000315 0.19668 0.01564 1.00000 0 20.91631 0.67963 18.33360 0.59575 4.11380 0.29864 3.60929 0.26204 57841.045442 0.000324 0.17764 0.01399 0.99107 0 22.71999 0.69452 19.98070 0.61072 4.03587 0.29297 3.54425 0.25732 57841.046079 0.000312 0.19357 0.01526 1.00000 0 21.47699 0.68210 18.91076 0.60059 4.15721 0.29986 3.65950 0.26394 57841.046718 0.000327 0.18284 0.01464 1.00000 0 21.51919 0.67557 18.95219 0.59489 3.93449 0.28983 3.46883 0.25552 57841.047363 0.000318 0.19794 0.01574 1.00000 0 20.34321 0.65880 18.07971 0.58547 4.02681 0.29235 3.57647 0.25966 57841.047991 0.000310 0.19006 0.01485 1.00000 0 22.23427 0.70019 19.63087 0.61814 4.22584 0.30207 3.72937 0.26652 57841.048651 0.000350 0.19365 0.01503 0.98347 0 20.05241 0.63101 17.57027 0.55302 3.88316 0.27540 3.40381 0.24141 57841.049360 0.000359 0.17536 0.01393 1.00000 0 20.48902 0.62381 18.03994 0.54918 3.59287 0.26371 3.15958 0.23184 57841.050057 0.000339 0.19170 0.01522 0.98291 0 20.27036 0.63666 17.85966 0.56090 3.88589 0.28333 3.42262 0.24948 57841.050743 0.000347 0.18089 0.01424 0.97500 0 21.25296 0.64718 18.61106 0.56669 3.84448 0.27897 3.36250 0.24413 57841.051414 0.000324 0.20046 0.01569 1.00000 0 20.65852 0.66689 17.86224 0.57662 4.14120 0.29520 3.58077 0.25525 57841.052077 0.000339 0.20223 0.01582 0.99145 0 19.45042 0.62675 17.07014 0.55002 3.93338 0.28049 3.45730 0.24645 57841.052734 0.000318 0.19404 0.01527 0.97273 0 21.68881 0.68171 19.06697 0.59931 4.20846 0.30360 3.69370 0.26640 57841.053608 0.000556 0.18117 0.01141 0.98438 0 20.81742 0.50712 18.11777 0.44133 3.77148 0.21901 3.28332 0.19066
