/* ** ** 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 59695.004304 0.000593 0.08821 0.01317 0.98537 0 6.25959 0.26420 5.63075 0.23766 0.55217 0.07906 0.49668 0.07112 59695.005930 0.001033 0.08208 0.00911 0.98372 0 6.84062 0.21043 6.15363 0.18930 0.56145 0.05989 0.50508 0.05388 59695.200650 0.000715 0.07694 0.01133 0.99190 0 7.27514 0.29166 5.24364 0.20978 0.55975 0.07929 0.40884 0.05782 59695.201770 0.000405 0.05208 0.01276 0.97857 0 7.58937 0.40760 5.32369 0.28587 0.39523 0.09452 0.27728 0.06627 59695.202866 0.000692 0.08475 0.01298 0.96653 0 7.01837 0.29705 4.96100 0.20998 0.59478 0.08752 0.42012 0.06182 59695.203966 0.000408 0.05453 0.01294 0.98582 0 7.29558 0.39319 5.14268 0.27715 0.39786 0.09195 0.28077 0.06489 59695.204692 0.000318 0.06403 0.01575 0.97273 0 7.88471 0.45974 5.54705 0.32344 0.50483 0.12064 0.35503 0.08485 59695.205968 0.000958 0.06788 0.00918 0.98792 0 7.72657 0.26598 5.40540 0.18605 0.52449 0.06863 0.36735 0.04806
