/* ** ** 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 58429.681878 0.000362 0.14885 0.01184 1.00000 0 32.31559 0.92186 21.10429 0.59161 4.81030 0.35712 3.13526 0.22992 58429.682674 0.000434 0.15089 0.01172 0.99333 0 29.82295 0.83817 17.59316 0.49387 4.50005 0.32590 2.65433 0.19213 58429.683539 0.000431 0.16294 0.01255 0.97987 0 26.69876 0.76946 16.77380 0.48330 4.35023 0.31081 2.73344 0.19531 58429.684381 0.000411 0.16045 0.01267 1.00000 0 27.64201 0.80777 17.19897 0.50258 4.43510 0.32525 2.75991 0.20239 58429.685174 0.000382 0.18267 0.01423 0.97727 0 27.26823 0.82893 16.95451 0.51539 4.98107 0.35726 3.09528 0.22203 58429.685984 0.000428 0.16868 0.01308 0.98649 0 25.85145 0.76617 16.14834 0.47843 4.36065 0.31236 2.71972 0.19483 58429.686840 0.000428 0.16533 0.01275 0.98649 0 26.71850 0.77921 16.69631 0.48682 4.41728 0.31526 2.76232 0.19713 58429.687717 0.000448 0.16856 0.01273 0.98442 0 26.97139 0.76134 16.86586 0.47608 4.54639 0.31837 2.84690 0.19929
