/* ** ** 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 57460.957385 0.000428 0.09315 0.01379 1.00000 0 12.18294 0.53147 7.27976 0.31751 1.13485 0.16051 0.67680 0.09571 57460.958203 0.000391 0.09736 0.01480 0.97778 0 11.64106 0.52350 7.64119 0.34363 1.13341 0.16458 0.74329 0.10788 57460.958947 0.000353 0.11283 0.01748 0.97541 0 11.14095 0.54479 7.28042 0.35599 1.25708 0.18483 0.81587 0.11997 57460.959723 0.000422 0.08420 0.01287 0.97260 0 12.48146 0.52374 8.11586 0.34056 1.05091 0.15452 0.68372 0.10054 57460.960620 0.000475 0.07576 0.01112 0.97561 0 12.74433 0.49721 8.24417 0.32161 0.96549 0.13655 0.62604 0.08854 57460.961418 0.000324 0.12148 0.01817 0.94643 0 12.02455 0.58496 7.80294 0.37961 1.46078 0.20662 0.94497 0.13364 57460.962110 0.000367 0.09914 0.01489 0.98425 0 12.42131 0.56188 8.00947 0.36230 1.23140 0.17642 0.79313 0.11362 57460.962775 0.000298 0.12762 0.01965 0.98058 0 11.74328 0.60526 7.64593 0.39402 1.49872 0.21740 0.97143 0.14099 57460.963473 0.000399 0.10338 0.01574 0.96377 0 10.91804 0.50285 7.13384 0.32854 1.12875 0.16382 0.73770 0.10707 57460.964251 0.000379 0.12557 0.01683 0.98473 0 11.99782 0.53885 7.84025 0.35213 1.50652 0.19025 0.98595 0.12449 57460.964948 0.000318 0.12114 0.01883 0.98182 0 11.41916 0.57482 7.42252 0.37358 1.38328 0.20344 0.89897 0.13219 57460.965579 0.000312 0.11996 0.01796 0.97222 0 12.02846 0.59188 7.96356 0.39185 1.44297 0.20407 0.95397 0.13491 57460.966201 0.000310 0.12421 0.01872 0.98131 0 12.10529 0.60545 7.83865 0.39202 1.50364 0.21373 0.97258 0.13828 57460.966841 0.000330 0.10838 0.01634 0.97368 0 12.56633 0.59061 8.24036 0.38728 1.36198 0.19512 0.89316 0.12795 57460.967532 0.000362 0.10073 0.01533 0.96800 0 12.27717 0.56241 8.03458 0.36808 1.23664 0.17945 0.81087 0.11768 57460.968322 0.000428 0.11718 0.01483 0.98649 0 12.54228 0.51399 8.24968 0.33808 1.46976 0.17603 0.96720 0.11583
