/* ** ** 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 54583.418796 0.000440 0.29855 0.04007 0.96711 0 4.14488 0.26510 3.31347 0.21191 1.23745 0.14601 0.98778 0.11655 54583.419545 0.000310 0.26074 0.04164 0.97196 0 4.53939 0.32952 3.67591 0.26684 1.18361 0.16838 0.95814 0.13630 54583.420153 0.000298 0.30870 0.04990 1.00000 0 3.94942 0.31328 3.19707 0.25360 1.21918 0.17171 0.98689 0.13899 54583.420801 0.000350 0.23985 0.03890 0.99174 0 4.17949 0.29796 3.38978 0.24166 1.00245 0.14604 0.81306 0.11844 54583.421478 0.000327 0.24135 0.03822 0.98230 0 4.58613 0.31902 3.71980 0.25875 1.10688 0.15746 0.89772 0.12771 54583.422100 0.000295 0.27372 0.04409 1.00000 0 4.42048 0.33386 3.56440 0.26918 1.20996 0.17212 0.97693 0.13897 54583.422734 0.000339 0.25088 0.04012 0.97436 0 4.30827 0.30769 3.45204 0.24655 1.08086 0.15468 0.86953 0.12443 54583.423463 0.000391 0.25581 0.03565 0.98519 0 4.76130 0.30118 3.85654 0.24395 1.21797 0.15127 0.98632 0.12249 54583.424262 0.000408 0.20847 0.03236 0.95745 0 4.38109 0.28028 3.55878 0.22767 0.91331 0.12916 0.74198 0.10493 54583.425014 0.000344 0.24162 0.03823 0.97479 0 4.44653 0.31325 3.60676 0.25409 1.07439 0.15219 0.87181 0.12350 54583.425720 0.000362 0.33873 0.05137 0.93600 0 3.61136 0.27408 2.93289 0.22259 1.22328 0.16062 0.99311 0.13040 54583.426403 0.000321 0.27623 0.04472 0.97297 0 4.15439 0.31296 3.34937 0.25229 1.14757 0.16446 0.92676 0.13282 54583.427089 0.000365 0.21423 0.03345 0.99206 0 4.65707 0.30798 3.74545 0.24769 0.99766 0.14110 0.80133 0.11333 54583.427757 0.000304 0.28884 0.04635 0.96190 0 4.27685 0.32418 3.45089 0.26155 1.23533 0.17471 0.99175 0.14025 54583.428481 0.000420 0.21583 0.03396 0.95172 0 4.10952 0.26862 3.32528 0.21734 0.88698 0.12692 0.71831 0.10279 54583.429323 0.000422 0.22662 0.03404 0.93151 0 4.31987 0.27445 3.51163 0.22310 0.97899 0.13322 0.79544 0.10825
