/* ** ** 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 55703.960821 0.000483 0.25937 0.04268 0.77815 0 4.78808 0.35167 2.92918 0.21141 1.24191 0.18287 0.75061 0.10938 55703.961724 0.000420 0.27202 0.04496 0.96552 0 4.54979 0.34629 2.54437 0.19363 1.23764 0.18157 0.69299 0.10160 55703.962615 0.000472 0.22534 0.03576 0.95092 0 4.83893 0.33142 2.81851 0.19302 1.09041 0.15611 0.63947 0.09152 55703.963570 0.000483 0.23174 0.03611 0.97605 0 4.68921 0.32015 2.70154 0.18440 1.08669 0.15219 0.62681 0.08777 55703.964389 0.000336 0.15884 0.03689 0.95690 0 4.27904 0.36384 2.47613 0.21055 0.67970 0.14690 0.39233 0.08478 55703.965147 0.000422 0.33485 0.05469 0.95890 0 3.75732 0.31079 2.16857 0.17939 1.25812 0.17720 0.72604 0.10226 55703.966064 0.000495 0.24445 0.03932 0.97076 0 4.21988 0.30003 2.46013 0.17489 1.03156 0.14885 0.59968 0.08647 55703.966987 0.000428 0.34561 0.05811 0.95946 0 3.41210 0.29140 1.99454 0.17031 1.17925 0.17078 0.69062 0.10003 55703.968032 0.000616 0.28706 0.04137 0.95645 0 3.81856 0.25955 2.19664 0.14929 1.09616 0.13932 0.63099 0.08018 55704.028112 0.000304 0.21961 0.03446 0.96190 0 5.40095 0.35742 4.48142 0.29646 1.18610 0.16874 0.98663 0.14035 55704.028760 0.000344 0.23305 0.03748 0.94958 0 4.47582 0.30502 3.69999 0.25212 1.04307 0.15196 0.86356 0.12578 55704.029509 0.000405 0.22856 0.03219 0.94992 0 5.06673 0.30200 4.20803 0.25081 1.15804 0.14776 0.96313 0.12287 55704.030247 0.000333 0.21170 0.03350 0.97391 0 5.01633 0.32999 4.16246 0.27381 1.06194 0.15285 0.88050 0.12673 55704.031147 0.000567 0.27470 0.03232 0.95408 0 4.35072 0.23915 3.61136 0.19849 1.19516 0.12433 0.99355 0.10335 55704.032875 0.001160 0.28975 0.02361 0.95761 0 4.23544 0.16256 3.54638 0.13612 1.22722 0.08819 1.02860 0.07391 55704.034362 0.000327 0.23293 0.03651 0.98230 0 4.68180 0.32203 3.93198 0.27045 1.09055 0.15358 0.91579 0.12897 55704.035033 0.000344 0.26476 0.03991 0.97479 0 4.34143 0.30284 3.65210 0.25476 1.14945 0.15360 0.96713 0.12924
