/* ** ** 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 55907.890563 0.000420 0.41042 0.03494 0.99310 0 7.56144 0.34735 6.70260 0.30787 3.10340 0.22240 2.75338 0.19728 55907.891402 0.000420 0.37129 0.03123 0.97931 0 8.57505 0.37424 7.49806 0.32721 3.18381 0.22888 2.78480 0.20019 55907.892238 0.000417 0.42532 0.03635 1.00000 0 7.41730 0.34756 6.51070 0.30509 3.15470 0.22548 2.76729 0.19777 55907.893072 0.000417 0.44016 0.03855 0.97917 0 7.21402 0.34749 6.30692 0.30380 3.17534 0.23225 2.77429 0.20293 55907.893911 0.000422 0.39122 0.03297 0.99315 0 8.09468 0.36442 7.04306 0.31708 3.16680 0.22558 2.75542 0.19627 55907.894715 0.000382 0.43965 0.03806 0.99242 0 7.85801 0.37551 6.86176 0.32792 3.45478 0.24934 3.01798 0.21784 55907.895456 0.000359 0.39373 0.03337 1.00000 0 9.11958 0.41282 8.12522 0.36781 3.59068 0.25728 3.19958 0.22927 55907.896205 0.000391 0.45289 0.03915 0.99259 0 7.47965 0.36054 6.58211 0.31729 3.38745 0.24307 2.97710 0.21364 55907.896981 0.000385 0.42039 0.03637 0.99248 0 8.08816 0.37997 7.08415 0.33277 3.40017 0.24706 2.97950 0.21647 55907.897756 0.000391 0.42403 0.03630 0.98519 0 8.01535 0.37545 7.03004 0.32924 3.39874 0.24353 2.98120 0.21359 55907.898535 0.000388 0.39436 0.03358 0.99254 0 8.39401 0.37948 7.51062 0.33947 3.31031 0.23882 2.96727 0.21405 55907.899339 0.000417 0.38271 0.03246 0.98611 0 8.15998 0.36381 7.26466 0.32385 3.12293 0.22534 2.77914 0.20048 55907.900155 0.000399 0.43049 0.03683 0.99275 0 7.82085 0.36938 6.80700 0.32150 3.36682 0.24018 2.93035 0.20904 55907.900965 0.000411 0.41872 0.03572 1.00000 0 7.64743 0.35662 6.69384 0.31210 3.20213 0.22870 2.79954 0.19992 55907.902062 0.000686 0.42799 0.02806 0.98734 0 7.55239 0.27085 6.74052 0.24170 3.23232 0.17737 2.88406 0.15824
