/* ** ** 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 59725.177667 0.000315 0.16240 0.01268 0.99083 0 25.65961 0.74269 22.49151 0.65099 4.16707 0.30208 3.65031 0.26464 59725.178251 0.000269 0.19142 0.01528 1.00000 0 24.97005 0.80099 22.00904 0.70601 4.77988 0.34927 4.21314 0.30786 59725.178819 0.000298 0.18249 0.01427 0.99029 0 24.13183 0.73911 21.30933 0.65266 4.40372 0.31675 3.88866 0.27970 59725.179415 0.000298 0.17595 0.01364 1.00000 0 25.10099 0.75942 22.05135 0.66708 4.41644 0.31522 3.87431 0.27649 59725.180011 0.000298 0.17651 0.01355 0.98058 0 25.49061 0.75721 22.51939 0.66895 4.49936 0.31860 3.97490 0.28146 59725.180604 0.000295 0.17273 0.01343 0.99020 0 25.68184 0.76568 22.69058 0.67650 4.43594 0.31864 3.91926 0.28152 59725.181217 0.000318 0.16656 0.01285 0.98182 0 25.15689 0.72943 22.22719 0.64448 4.19026 0.29945 3.70234 0.26458 59725.181854 0.000318 0.17191 0.01330 1.00000 0 23.88619 0.71462 21.10201 0.63133 4.10636 0.29305 3.62777 0.25890 59725.182464 0.000292 0.19317 0.01505 1.00000 0 23.26083 0.73731 20.55713 0.65161 4.49329 0.31985 3.97087 0.28267 59725.183043 0.000286 0.18607 0.01439 1.00000 0 24.78673 0.77188 21.78604 0.67842 4.61197 0.32661 4.05520 0.28715 59725.183625 0.000295 0.18997 0.01487 0.97059 0 24.00346 0.74732 21.05975 0.65563 4.55999 0.32757 3.99844 0.28721 59725.184218 0.000298 0.17799 0.01410 1.00000 0 24.14032 0.74224 21.32865 0.65579 4.29678 0.31357 3.79635 0.27705 59725.184826 0.000310 0.17257 0.01345 1.00000 0 24.30544 0.72977 21.48013 0.64494 4.19439 0.30169 3.70695 0.26663 59725.185451 0.000315 0.16080 0.01240 0.99083 0 25.99543 0.74770 22.84470 0.65705 4.18012 0.29911 3.67640 0.26304 59725.186047 0.000281 0.18747 0.01462 1.00000 0 25.17279 0.79291 21.95572 0.69160 4.71916 0.33675 4.11396 0.29360 59725.186897 0.000570 0.15618 0.00910 0.99492 0 26.10810 0.55904 22.74932 0.48709 4.07764 0.22082 3.55478 0.19245
