/* ** ** 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 55362.898859 0.000312 0.15272 0.02325 0.99074 0 6.85610 0.38640 6.14176 0.34615 1.04709 0.14809 0.93614 0.13239 55362.899554 0.000382 0.13467 0.02027 0.96212 0 6.56382 0.33767 5.86942 0.30194 0.88393 0.12501 0.78871 0.11154 55362.900364 0.000428 0.12982 0.01972 0.98649 0 5.92677 0.30413 5.30892 0.27242 0.76940 0.10999 0.68815 0.09834 55362.901107 0.000315 0.15486 0.02382 1.00000 0 6.56897 0.37382 5.88230 0.33472 1.01725 0.14540 0.91116 0.13019 55362.901735 0.000312 0.16498 0.02545 1.00000 0 6.23112 0.36222 5.57425 0.32404 1.02802 0.14689 0.91959 0.13140 55362.902395 0.000347 0.15005 0.02113 0.99167 0 7.31422 0.37187 6.57317 0.33419 1.09749 0.14413 0.98610 0.12951 55362.903084 0.000341 0.13858 0.02127 0.94915 0 7.05864 0.36750 6.34776 0.33049 0.97818 0.14123 0.87916 0.12693 55362.903804 0.000379 0.15841 0.02274 0.97357 0 6.38562 0.33339 5.72026 0.29864 1.01153 0.13528 0.90676 0.12121 55362.968347 0.001088 0.17417 0.01370 0.97074 0 6.84778 0.20468 6.15952 0.18409 1.19266 0.08680 1.07247 0.07808 55362.969786 0.000350 0.14185 0.02170 0.98347 0 6.54494 0.35107 5.86717 0.31468 0.92837 0.13304 0.83313 0.11935 55362.970439 0.000304 0.16251 0.02508 0.97143 0 6.60875 0.37834 5.97961 0.34233 1.07401 0.15389 0.97199 0.13924 55362.971137 0.000394 0.17194 0.02275 0.98529 0 6.46778 0.32854 5.85270 0.29729 1.11208 0.13587 1.00167 0.12237
