/* ** ** 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 59209.588676 0.000460 0.19157 0.01485 0.98742 0 14.72278 0.45546 13.37993 0.41392 2.82038 0.20055 2.56716 0.18254 59209.589587 0.000451 0.19469 0.01542 0.98077 0 14.53015 0.46004 13.20013 0.41791 2.82891 0.20536 2.57125 0.18669 59209.590510 0.000472 0.18547 0.01465 0.98773 0 14.54591 0.45282 13.15491 0.40951 2.69787 0.19587 2.44349 0.17741 59209.591465 0.000483 0.19808 0.01549 0.98204 0 13.52861 0.42863 12.28809 0.38932 2.67971 0.19155 2.43316 0.17389 59209.592405 0.000457 0.18110 0.01444 0.99367 0 15.11760 0.46522 13.71744 0.42206 2.73781 0.20144 2.48260 0.18267 59209.593372 0.000509 0.16742 0.01313 0.98864 0 14.80487 0.43804 13.49737 0.39937 2.47865 0.17996 2.26093 0.16416 59209.594402 0.000521 0.16315 0.01284 0.98333 0 14.82051 0.43305 13.56040 0.39623 2.41790 0.17673 2.21235 0.16170 59209.595394 0.000472 0.19048 0.01490 0.98773 0 14.15171 0.44455 12.94583 0.40667 2.69566 0.19315 2.46605 0.17669 59209.596448 0.000582 0.15390 0.01184 0.99005 0 14.17225 0.39735 12.96371 0.36347 2.18115 0.15628 1.99515 0.14295 59209.597799 0.000770 0.20146 0.01175 0.99248 0 14.87081 0.35548 13.57369 0.32447 2.99587 0.15932 2.73465 0.14543
