/* ** ** 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 58103.437945 0.000431 0.15182 0.01153 0.98658 0 19.27121 0.53398 17.95435 0.49749 2.92567 0.20688 2.72563 0.19273 58103.438851 0.000475 0.13227 0.01034 0.98780 0 19.64936 0.51514 18.16572 0.47624 2.59907 0.19133 2.40315 0.17688 58103.439754 0.000428 0.14841 0.01126 1.00000 0 19.81767 0.54225 18.45891 0.50507 2.94109 0.20823 2.73943 0.19395 58103.440645 0.000463 0.13498 0.01018 1.00000 0 19.91862 0.52243 18.55254 0.48660 2.68858 0.19011 2.50417 0.17707 58103.441626 0.000518 0.12739 0.00962 0.97765 0 19.28080 0.49066 17.89590 0.45536 2.45610 0.17467 2.28025 0.16216 58103.442618 0.000475 0.13051 0.00995 0.99390 0 20.21652 0.52342 18.69127 0.48389 2.63853 0.18928 2.44051 0.17510 58103.443596 0.000503 0.12299 0.00920 0.99425 0 20.44366 0.51017 18.93096 0.47239 2.51431 0.17735 2.32757 0.16417 58103.444612 0.000512 0.12983 0.00987 0.98870 0 19.33794 0.49312 17.70312 0.45143 2.51060 0.17978 2.29823 0.16455 58103.445596 0.000472 0.13118 0.00998 1.00000 0 20.03160 0.52029 18.58231 0.48263 2.62778 0.18799 2.43817 0.17438 58103.446507 0.000440 0.13673 0.01054 0.99342 0 20.58822 0.54782 19.09951 0.50823 2.81501 0.20365 2.61044 0.18885 58103.447387 0.000440 0.14027 0.01089 0.99342 0 20.14248 0.54276 18.54294 0.49962 2.82538 0.20562 2.59970 0.18916 58103.448270 0.000443 0.14391 0.01128 0.99346 0 19.42073 0.53415 17.87927 0.49169 2.79482 0.20517 2.57443 0.18898 58103.449172 0.000460 0.13357 0.01028 0.98742 0 20.46754 0.53556 18.90479 0.49462 2.73387 0.19787 2.52587 0.18282 58103.450509 0.000877 0.13681 0.00757 0.98020 0 19.95736 0.38235 18.47436 0.35392 2.73029 0.14167 2.52528 0.13102
