/* ** ** 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 55264.980800 0.000376 0.34619 0.01299 1.00000 0 50.00766 0.94435 43.95801 0.83004 17.31210 0.56134 15.21010 0.49324 55264.981555 0.000379 0.35061 0.01320 1.00000 0 48.40921 0.93148 43.07213 0.82878 16.97293 0.54926 15.10162 0.48870 55264.982331 0.000396 0.32730 0.01208 1.00000 0 50.15787 0.92462 44.63350 0.82279 16.41647 0.52520 14.60835 0.46736 55264.983115 0.000388 0.33709 0.01258 1.00000 0 49.52709 0.92908 43.85527 0.82263 16.69505 0.53889 14.78594 0.47723 55264.983905 0.000402 0.32395 0.01209 0.98563 0 50.01931 0.92396 44.50767 0.82215 16.20360 0.52573 14.41811 0.46780 55264.984698 0.000391 0.33472 0.01260 1.00000 0 49.00209 0.91606 43.60268 0.81513 16.40216 0.53580 14.59487 0.47676 55264.985482 0.000394 0.32917 0.01227 1.00000 0 49.64943 0.91892 44.19234 0.81792 16.34290 0.52887 14.54642 0.47073 55264.986281 0.000405 0.31212 0.01162 1.00000 0 50.67326 0.91621 45.08974 0.81525 15.81630 0.51479 14.07360 0.45807 55264.987056 0.000370 0.34437 0.01298 1.00000 0 50.27497 0.95697 44.74413 0.85169 17.31338 0.56322 15.40865 0.50125 55264.987823 0.000396 0.33427 0.01246 1.00000 0 48.78552 0.91050 43.41820 0.81033 16.30747 0.52635 14.51335 0.46844 55264.988595 0.000376 0.35011 0.01312 1.00000 0 49.09593 0.93549 43.68539 0.83239 17.18921 0.55481 15.29484 0.49366 55264.989330 0.000359 0.35187 0.01325 1.00000 0 50.90689 0.97824 45.29527 0.87041 17.91257 0.57997 15.93798 0.51604 55264.990077 0.000388 0.34987 0.01303 1.00000 0 47.83191 0.90757 42.55978 0.80753 16.73503 0.53622 14.89056 0.47712 55264.991052 0.000587 0.33970 0.01045 1.00000 0 48.27487 0.74487 42.95307 0.66276 16.39877 0.43662 14.59099 0.38849
