/* ** ** 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 55614.958285 0.000417 0.10790 0.02540 0.95139 0 3.18504 0.23387 2.70228 0.19842 0.34367 0.07685 0.29246 0.06540 55614.959202 0.000501 0.07861 0.01824 0.94220 0 3.65308 0.22610 3.12833 0.19362 0.28716 0.06421 0.24581 0.05496 55614.960249 0.000547 0.08378 0.01950 0.93674 0 3.16305 0.20373 2.70127 0.17399 0.26501 0.05926 0.22631 0.05060 55614.961248 0.000451 0.08846 0.02065 0.97400 0 3.50547 0.23405 2.98460 0.19928 0.31010 0.06935 0.26369 0.05896 55614.962425 0.000726 0.05995 0.01422 0.94420 0 3.20936 0.17848 2.73051 0.15184 0.19239 0.04438 0.16446 0.03794 55614.963461 0.000310 0.13300 0.03217 1.00000 0 3.25938 0.27111 2.78392 0.23156 0.43350 0.09847 0.36936 0.08389 55614.964173 0.000402 0.10377 0.02510 0.97122 0 3.27161 0.23894 2.78276 0.20320 0.33949 0.07830 0.28872 0.06661 55614.964969 0.000394 0.11223 0.02647 0.96324 0 3.19200 0.23962 2.71961 0.20413 0.35822 0.08011 0.30585 0.06839 55614.965805 0.000443 0.09494 0.02288 0.96732 0 3.25518 0.22647 2.77749 0.19320 0.30903 0.07131 0.26336 0.06076 55614.966687 0.000440 0.09435 0.02272 0.95395 0 3.37489 0.23251 2.86513 0.19738 0.31842 0.07346 0.26881 0.06202 55614.967680 0.000553 0.08274 0.01931 0.94241 0 3.23544 0.20388 2.76721 0.17437 0.26769 0.06016 0.22767 0.05118 55614.969182 0.000949 0.06611 0.01339 0.96646 0 2.91536 0.14703 2.49572 0.12586 0.19275 0.03780 0.16431 0.03222
