/* ** ** 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 56383.274880 0.000443 0.19924 0.00702 0.99346 0 70.81429 1.00970 65.61681 0.93555 14.10886 0.45458 13.07715 0.42131 56383.275763 0.000440 0.20370 0.00722 1.00000 0 68.24264 0.99211 63.74218 0.92667 13.90124 0.44947 12.98489 0.41987 56383.276680 0.000477 0.18644 0.00655 1.00000 0 68.54196 0.95077 64.28960 0.89178 12.77893 0.41278 11.98612 0.38717 56383.277609 0.000451 0.19689 0.00697 1.00000 0 68.55888 0.98110 64.30484 0.92022 13.49853 0.43737 12.66096 0.41024 56383.278517 0.000457 0.19534 0.00691 1.00000 0 68.22671 0.96956 63.99341 0.90941 13.32764 0.43184 12.50069 0.40504 56383.279443 0.000469 0.19374 0.00685 1.00000 0 67.41366 0.95392 63.23107 0.89474 13.06049 0.42316 12.25017 0.39690 56383.280358 0.000446 0.20226 0.00715 1.00000 0 67.70386 0.98056 63.50344 0.91972 13.69380 0.44175 12.84422 0.41435 56383.281258 0.000454 0.19962 0.00702 1.00000 0 67.64222 0.97004 63.44183 0.90981 13.50294 0.43391 12.66449 0.40697 56383.282157 0.000446 0.20348 0.00722 1.00000 0 67.40445 0.97916 63.22261 0.91842 13.71532 0.44370 12.86441 0.41617 56383.283066 0.000463 0.19222 0.00674 1.00000 0 68.92542 0.97145 64.64889 0.91117 13.24908 0.42575 12.42703 0.39934 56383.283989 0.000460 0.19206 0.00673 1.00000 0 69.42686 0.97827 65.11956 0.91758 13.33435 0.42794 12.50707 0.40139 56383.285227 0.000773 0.19297 0.00523 0.99625 0 68.87181 0.75103 64.59902 0.70444 13.29047 0.32959 12.46593 0.30914
