/* ** ** 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 59026.984320 0.000417 0.26602 0.04280 0.97222 0 3.14181 0.23109 2.65932 0.19558 0.83577 0.11960 0.70799 0.10132 59026.985054 0.000318 0.16804 0.03966 0.96364 0 2.75550 0.24755 2.36225 0.21222 0.46304 0.10104 0.39689 0.08661 59026.985798 0.000425 0.27507 0.04435 0.98639 0 2.91596 0.22116 2.49842 0.18949 0.80210 0.11411 0.68719 0.09776 59026.986663 0.000440 0.27099 0.04332 0.97368 0 2.94387 0.21803 2.51995 0.18663 0.79775 0.11301 0.68326 0.09680 59026.987586 0.000483 0.25211 0.04028 0.96407 0 2.86523 0.20842 2.45380 0.17850 0.72236 0.10277 0.61890 0.08805 59026.988524 0.000454 0.23378 0.03690 0.98089 0 3.27575 0.22806 2.80881 0.19556 0.76580 0.10849 0.65664 0.09302 59026.989351 0.000373 0.33364 0.05468 0.96899 0 2.80289 0.23218 2.40153 0.19893 0.93516 0.13225 0.80133 0.11333 59026.990150 0.000425 0.29027 0.04665 0.96599 0 2.83566 0.21639 2.42970 0.18541 0.82311 0.11641 0.70540 0.09976 59026.991064 0.000489 0.22290 0.03520 0.98817 0 3.12146 0.21412 2.67674 0.18362 0.69579 0.09898 0.59666 0.08488 59026.992077 0.000524 0.20539 0.03196 0.97238 0 3.23235 0.20965 2.77067 0.17970 0.66388 0.09389 0.56913 0.08049 59026.993130 0.000530 0.22449 0.03558 0.96175 0 2.92701 0.19924 2.50803 0.17072 0.65708 0.09403 0.56318 0.08060
