/* ** ** 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 57432.303707 0.000877 0.11680 0.00904 0.98020 0 12.44559 0.30469 11.24406 0.27524 1.45364 0.10673 1.31392 0.09646 57432.305580 0.000995 0.10604 0.00807 0.97384 0 12.18464 0.28344 11.08020 0.25774 1.29202 0.09367 1.17526 0.08521 57432.307475 0.000900 0.11456 0.00877 0.98714 0 12.39632 0.30068 11.26109 0.27313 1.42010 0.10306 1.28983 0.09361 57432.309260 0.000885 0.11806 0.00903 0.99673 0 12.07016 0.29949 10.98938 0.27267 1.42503 0.10304 1.29742 0.09382 57432.311051 0.000906 0.11654 0.00887 0.99681 0 11.98967 0.29498 10.87343 0.26750 1.39725 0.10067 1.26747 0.09132 57432.312877 0.000920 0.11302 0.00849 0.99057 0 12.39558 0.29781 11.21509 0.26944 1.40100 0.09970 1.26644 0.09011 57432.314876 0.001079 0.11293 0.00792 0.98391 0 12.37616 0.27607 11.23626 0.25063 1.39768 0.09294 1.26929 0.08439
