/* ** ** 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 59315.136005 0.000469 0.14479 0.01095 0.97531 0 19.24446 0.51518 17.49460 0.46828 2.78644 0.19704 2.53587 0.17931 59315.136904 0.000431 0.15370 0.01185 0.99329 0 19.09105 0.53792 17.41766 0.49076 2.93428 0.21049 2.67854 0.19214 59315.137827 0.000492 0.13661 0.01044 0.98824 0 18.84474 0.49793 17.27341 0.45641 2.57433 0.18467 2.35967 0.16927 59315.138771 0.000451 0.15201 0.01190 0.98718 0 18.21098 0.50956 16.69266 0.46708 2.76824 0.20245 2.53744 0.18557 59315.139665 0.000443 0.15598 0.01208 0.98039 0 18.49195 0.52226 16.88022 0.47675 2.88446 0.20790 2.63340 0.18982 59315.140582 0.000475 0.14290 0.01093 0.98780 0 18.85381 0.50742 17.21882 0.46338 2.69429 0.19282 2.45943 0.17597 59315.141528 0.000472 0.15241 0.01171 0.99387 0 17.60215 0.49176 16.13649 0.45081 2.68282 0.19196 2.45943 0.17597 59315.142402 0.000402 0.16835 0.01306 0.99281 0 18.73455 0.55319 17.17516 0.50715 3.15394 0.22617 2.89142 0.20734 59315.143328 0.000524 0.12985 0.01005 1.00000 0 18.23175 0.47407 16.71210 0.43455 2.36732 0.17267 2.17000 0.15827 59315.144260 0.000408 0.15729 0.01237 1.00000 0 19.21978 0.55437 17.62004 0.50823 3.02303 0.22108 2.77139 0.20268 59315.145244 0.000576 0.14037 0.01003 0.96985 0 18.63862 0.46268 17.08659 0.42416 2.61625 0.17523 2.39837 0.16063
