/* ** ** 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 59968.123439 0.000182 0.19455 0.01518 1.00000 0 38.17659 1.19974 32.87498 1.03304 7.42712 0.53057 6.39826 0.45706 59968.123827 0.000205 0.18154 0.01406 1.00000 0 35.88921 1.10876 31.12633 0.96157 6.51530 0.46273 5.64516 0.40089 59968.124252 0.000220 0.15917 0.01210 1.00000 0 38.41319 1.09409 33.63058 0.95787 6.11409 0.43094 5.35285 0.37729 59968.124675 0.000203 0.17422 0.01365 1.00000 0 38.13012 1.15108 32.57532 0.98334 6.64312 0.48023 5.67458 0.41022 59968.125094 0.000217 0.16505 0.01292 0.98667 0 37.65777 1.10027 32.23657 0.94190 6.21542 0.45152 5.31370 0.38615 59968.125499 0.000188 0.19949 0.01565 1.00000 0 35.77357 1.15713 30.74018 0.99429 7.13630 0.51021 6.13759 0.43883 59968.125901 0.000214 0.17015 0.01321 0.98649 0 36.51567 1.08726 31.95643 0.95151 6.21317 0.44537 5.43753 0.38978 59968.126312 0.000197 0.18171 0.01431 1.00000 0 36.81717 1.13483 31.95253 0.98480 6.68995 0.48479 5.81202 0.42126 59968.126709 0.000200 0.18699 0.01465 0.98551 0 36.20580 1.11875 31.27435 0.96635 6.77026 0.48751 5.83942 0.42037 59968.127099 0.000191 0.19092 0.01503 1.00000 0 36.06241 1.14839 31.51302 1.00352 6.88498 0.49564 6.01637 0.43310 59968.127542 0.000252 0.17538 0.01252 0.99459 0 36.24892 0.99446 31.73886 0.87073 6.35738 0.41909 5.56620 0.36693 59968.188994 0.000367 0.18889 0.01506 0.98425 0 31.64662 0.99676 16.67448 0.52387 5.97770 0.43796 3.16524 0.23116 59968.189753 0.000391 0.18766 0.01504 0.98519 0 31.57780 1.00023 15.62913 0.49503 5.92596 0.43627 2.92966 0.21569 59968.190548 0.000405 0.17137 0.01337 0.97857 0 33.37386 0.99278 16.83128 0.50061 5.71912 0.41262 2.88435 0.20810 59968.191361 0.000408 0.16588 0.01309 0.99291 0 33.41433 0.99244 16.87441 0.50118 5.54289 0.40531 2.79630 0.20448 59968.192145 0.000376 0.17915 0.01433 1.00000 0 33.08913 1.03314 16.73445 0.52251 5.92804 0.43641 2.99727 0.22066 59968.193141 0.000613 0.19438 0.01190 0.99057 0 31.77720 0.78619 16.07697 0.39774 6.17692 0.34602 3.12344 0.17492
