/* ** ** 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 56708.034732 0.000613 0.13363 0.01032 0.98585 0 18.09158 0.47709 14.07220 0.37088 2.41758 0.17543 1.88202 0.13668 56708.035907 0.000561 0.15191 0.01161 0.98454 0 17.53767 0.48741 13.75912 0.38238 2.66418 0.18970 2.08814 0.14864 56708.036989 0.000521 0.16784 0.01317 0.98333 0 16.81745 0.50044 13.23709 0.39390 2.82263 0.20499 2.22227 0.16140 56708.038062 0.000553 0.16489 0.01293 1.00000 0 15.92804 0.47190 12.47584 0.36960 2.62631 0.19072 2.05938 0.14957 56708.039457 0.000842 0.13936 0.00921 0.98790 0 17.34138 0.39761 13.51968 0.30996 2.41678 0.14979 1.88512 0.11682 56708.101345 0.000558 0.15609 0.01214 0.97409 0 17.80658 0.50460 13.43057 0.38007 2.77939 0.20136 2.10330 0.15230 56708.102636 0.000732 0.11969 0.00930 0.98024 0 17.25278 0.43064 13.14620 0.32796 2.06502 0.15198 1.57174 0.11563 56708.104002 0.000634 0.13558 0.01037 0.99543 0 17.84628 0.47255 13.46451 0.35648 2.41967 0.17365 1.83136 0.13140 56708.105220 0.000584 0.13923 0.01127 0.99010 0 18.06797 0.49668 13.66558 0.37554 2.51556 0.19153 1.90364 0.14481 56708.107051 0.001247 0.12949 0.00734 0.99304 0 17.40912 0.33204 13.11816 0.25015 2.25426 0.12030 1.69753 0.09061
