/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 57663.265921 0.000359 0.29052 0.04672 0.96774 0 3.71660 0.28155 2.91003 0.22024 1.07973 0.15315 0.84286 0.11938 57663.266830 0.000550 0.16815 0.02585 0.97895 0 4.20136 0.24501 3.19168 0.18611 0.70645 0.10050 0.53577 0.07621 57663.267932 0.000553 0.17214 0.02646 0.94241 0 4.22082 0.24617 3.21409 0.18746 0.72656 0.10334 0.55363 0.07875 57663.268861 0.000376 0.23831 0.03812 0.97692 0 4.28904 0.29948 3.26084 0.22768 1.02213 0.14711 0.77659 0.11176 57663.269714 0.000477 0.19740 0.03073 0.98182 0 4.09432 0.25919 3.11769 0.19736 0.80822 0.11497 0.61514 0.08750 57663.270637 0.000446 0.20775 0.03247 1.00000 0 4.13995 0.27534 3.12761 0.20802 0.86006 0.12163 0.65043 0.09199 57663.271462 0.000379 0.24984 0.04023 0.97710 0 4.06129 0.29319 3.08170 0.22247 1.01469 0.14603 0.77052 0.11089 57663.272284 0.000443 0.19820 0.03116 0.96732 0 4.42600 0.28018 3.36546 0.21304 0.87722 0.12624 0.66640 0.09590 57663.273224 0.000498 0.18455 0.02883 0.95349 0 4.31002 0.26211 3.26172 0.19835 0.79539 0.11446 0.60138 0.08655 57663.274159 0.000437 0.20918 0.03285 0.96026 0 4.30911 0.27917 3.26811 0.21172 0.90136 0.12896 0.68372 0.09782 57663.275076 0.000480 0.18008 0.02796 0.96988 0 4.52978 0.27297 3.41612 0.20585 0.81573 0.11671 0.61578 0.08810 57663.276066 0.000509 0.18362 0.02844 0.96591 0 4.22737 0.25919 3.19384 0.19582 0.77624 0.11042 0.58620 0.08338 57663.277168 0.000593 0.24275 0.03049 0.98049 0 4.31161 0.23992 3.26327 0.18158 1.04663 0.11788 0.79224 0.08922
