/* ** ** 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 59339.242777 0.000310 0.16605 0.02548 0.96262 0 16.47405 0.95866 5.86972 0.34146 2.73548 0.38841 0.98181 0.13927 59339.243417 0.000330 0.16747 0.02475 0.97368 0 15.45016 0.87582 5.89409 0.33398 2.58749 0.35315 0.98324 0.13418 59339.244806 0.001059 0.19396 0.01535 0.96448 0 14.91708 0.47425 5.77474 0.18346 2.89330 0.20967 1.11705 0.08089 59339.246163 0.000298 0.16201 0.02537 0.98058 0 15.43264 0.90292 5.99464 0.35065 2.50029 0.36318 0.97108 0.14101 59339.246898 0.000437 0.15902 0.02077 0.97351 0 15.82978 0.76565 6.10914 0.29554 2.51728 0.30542 0.96644 0.11730 59339.247968 0.000634 0.15509 0.01643 0.98174 0 16.17489 0.63133 6.33251 0.24716 2.50850 0.24709 0.98244 0.09675 59339.248929 0.000327 0.13766 0.02105 0.96460 0 17.08930 0.91322 6.61357 0.35344 2.35254 0.33713 0.90938 0.13031 59339.249869 0.000613 0.16524 0.01781 0.96698 0 15.23847 0.62437 6.00649 0.24609 2.51799 0.25100 0.99169 0.09883 59339.251620 0.001137 0.18394 0.01381 0.92875 0 16.67311 0.48598 6.56531 0.19134 3.06689 0.21215 1.20849 0.08361
