/* ** ** 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 58247.972084 0.000501 0.16769 0.01310 0.97688 0 15.20368 0.44443 13.88950 0.40602 2.54953 0.18463 2.32918 0.16867 58247.973103 0.000518 0.16680 0.01296 0.95531 0 15.17162 0.44066 13.83552 0.40183 2.53060 0.18238 2.31017 0.16650 58247.974142 0.000521 0.15124 0.01161 0.98333 0 16.26914 0.45209 14.88433 0.41361 2.46062 0.17604 2.25113 0.16105 58247.975146 0.000483 0.17434 0.01362 0.98802 0 15.05694 0.45461 13.72668 0.41443 2.62496 0.18917 2.39418 0.17255 58247.976187 0.000558 0.14405 0.01115 0.98964 0 15.81519 0.43224 14.40644 0.39370 2.27811 0.16491 2.07451 0.15016 58247.977264 0.000518 0.16690 0.01276 0.98324 0 14.94811 0.43376 13.64351 0.39590 2.49481 0.17641 2.27652 0.16097 58247.978268 0.000486 0.16536 0.01287 0.98810 0 15.72850 0.46115 14.39072 0.42193 2.60091 0.18745 2.37975 0.17151 58247.979263 0.000509 0.16208 0.01254 0.99432 0 15.27590 0.44355 13.97675 0.40583 2.47597 0.17759 2.26541 0.16249 58247.980290 0.000518 0.15786 0.01218 0.99441 0 15.42319 0.43953 14.10951 0.40209 2.43471 0.17464 2.22722 0.15975 58247.981373 0.000564 0.15979 0.01171 0.99487 0 15.84981 0.42673 14.50095 0.39041 2.53270 0.17265 2.31707 0.15795
