/* ** ** 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 58415.002760 0.000436 0.22076 0.03045 0.99892 1 17.65865 1.05362 3.91914 0.23383 3.89825 0.48487 0.86528 0.10762 58415.004046 0.000336 0.17846 0.01375 0.98276 0 21.63021 0.65314 19.73594 0.59586 3.86016 0.27358 3.52010 0.24944 58415.004755 0.000373 0.15024 0.01165 0.98450 0 23.03766 0.63944 20.63764 0.57282 3.46115 0.25050 3.10057 0.22440 58415.005452 0.000324 0.18672 0.01451 0.99107 0 21.22130 0.65305 19.20641 0.59101 3.96234 0.28279 3.58477 0.25584 58415.006112 0.000336 0.17544 0.01376 1.00000 0 21.46654 0.64846 19.33200 0.58395 3.76615 0.27260 3.39459 0.24568 58415.006786 0.000339 0.17627 0.01393 0.97436 0 21.37395 0.64276 19.43405 0.58440 3.76749 0.27525 3.42995 0.25057 58415.007489 0.000365 0.15930 0.01252 1.00000 0 21.64948 0.62715 19.48115 0.56435 3.44880 0.25198 3.10329 0.22671 58415.008210 0.000356 0.16555 0.01276 0.97561 0 22.54259 0.65128 20.19308 0.58340 3.73194 0.26677 3.34301 0.23897 58415.008890 0.000324 0.18831 0.01498 1.00000 0 20.58444 0.64842 18.54074 0.58400 3.87627 0.28316 3.49120 0.25505 58415.009544 0.000330 0.17398 0.01363 0.99123 0 22.12884 0.66372 20.03311 0.60084 3.85007 0.27866 3.48471 0.25220 58415.010209 0.000336 0.17748 0.01374 0.98276 0 21.72863 0.65234 19.64987 0.58987 3.85634 0.27526 3.49043 0.24911 58415.011161 0.000616 0.17575 0.01009 0.98497 0 21.73627 0.48197 19.63790 0.43542 3.82023 0.20231 3.44949 0.18265
