/* ** ** 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 57116.944793 0.000136 0.22301 0.01833 1.00000 0 49.05626 1.72275 37.13540 1.30008 10.93990 0.81303 8.35677 0.61890 57116.945456 0.000527 0.20573 0.00740 1.00000 0 60.51366 0.89352 52.35300 0.77272 12.44919 0.40848 10.76738 0.35325 57116.946486 0.000503 0.22178 0.00805 1.00000 0 60.66999 0.93181 50.94197 0.78243 13.45563 0.44227 11.29730 0.37135 57116.947490 0.000501 0.22458 0.00803 0.99422 0 61.45767 0.93751 51.28207 0.78219 13.80202 0.44633 11.51485 0.37232 57116.948115 0.000124 0.18926 0.01472 0.97674 0 61.32997 1.88245 51.15865 1.57016 11.60718 0.82940 9.68415 0.69190 57116.948769 0.000530 0.21604 0.00783 0.99454 0 59.27647 0.89826 49.77708 0.75428 12.80638 0.42188 10.75669 0.35435 57116.949811 0.000512 0.22219 0.00794 1.00000 0 60.33716 0.91970 50.54488 0.77040 13.40611 0.43348 11.22935 0.36308 57116.950835 0.000512 0.22021 0.00792 1.00000 0 60.23579 0.91546 50.54943 0.76826 13.26475 0.43251 11.12781 0.36280 57116.951891 0.000544 0.20689 0.00740 1.00000 0 60.61752 0.89540 50.59823 0.74739 12.54111 0.40827 10.47124 0.34087 57116.952953 0.000518 0.21640 0.00785 1.00000 0 60.16794 0.90860 50.49306 0.76248 13.02053 0.42915 10.92578 0.36011 57116.953963 0.000492 0.23148 0.00828 1.00000 0 59.93119 0.93159 50.46239 0.78442 13.87291 0.44715 11.67962 0.37648 57116.954955 0.000501 0.22324 0.00803 1.00000 0 60.78081 0.93166 50.99754 0.78168 13.56867 0.44153 11.39073 0.37061 57116.955951 0.000495 0.22716 0.00826 1.00000 0 60.06159 0.93218 50.45477 0.78297 13.64386 0.44857 11.45433 0.37656 57116.957027 0.000582 0.21987 0.00749 1.00000 0 58.68729 0.85035 49.12236 0.71168 12.90372 0.39805 10.80036 0.33309
