/* ** ** 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 55152.952556 0.000501 0.21593 0.03404 0.97110 0 3.21667 0.21269 2.72983 0.18050 0.69458 0.09941 0.59000 0.08443 55152.953522 0.000466 0.24708 0.03919 0.95031 0 3.11007 0.21822 2.63353 0.18477 0.76842 0.10932 0.65126 0.09265 55152.954385 0.000396 0.29144 0.04730 0.95620 0 3.04102 0.23273 2.59610 0.19868 0.88626 0.12683 0.75664 0.10828 55152.955166 0.000385 0.27489 0.04428 0.98496 0 3.26598 0.24667 2.76290 0.20867 0.89778 0.12772 0.76064 0.10821 55152.955907 0.000356 0.33397 0.05467 0.98374 0 2.92367 0.24108 2.48236 0.20470 0.97641 0.13809 0.82782 0.11707 55152.956604 0.000341 0.31479 0.05212 0.98305 0 3.16188 0.25847 2.70012 0.22072 0.99534 0.14330 0.84997 0.12237 55152.957307 0.000362 0.29417 0.04767 0.97600 0 3.25195 0.25235 2.77642 0.21545 0.95664 0.13609 0.81675 0.11619 55152.958091 0.000422 0.25439 0.04100 0.98630 0 3.17290 0.22990 2.69585 0.19533 0.80716 0.11621 0.68470 0.09857 55152.958899 0.000385 0.27214 0.04355 0.98496 0 3.29070 0.24643 2.80948 0.21040 0.89555 0.12665 0.76463 0.10814 55152.959688 0.000405 0.26785 0.04322 0.97857 0 3.16454 0.23577 2.70137 0.20126 0.84762 0.12130 0.72350 0.10354 55152.960490 0.000396 0.26246 0.04262 0.97080 0 3.29078 0.24174 2.80931 0.20637 0.86369 0.12509 0.73739 0.10680 55152.961315 0.000428 0.26471 0.04216 0.94595 0 3.16678 0.23201 2.70322 0.19804 0.83827 0.11855 0.71548 0.10118 55152.962105 0.000362 0.33021 0.05480 0.97600 0 2.88187 0.23799 2.44962 0.20228 0.95162 0.13700 0.80817 0.11635 55152.962819 0.000353 0.34804 0.05359 0.94262 0 3.32577 0.25731 2.83992 0.21972 1.15750 0.15411 0.98841 0.13160 55152.963661 0.000489 0.21358 0.03336 0.99408 0 3.27153 0.21699 2.79144 0.18515 0.69873 0.09882 0.59623 0.08432 55152.964694 0.000544 0.30083 0.04017 0.96277 0 3.16652 0.20343 2.68108 0.17224 0.95258 0.11150 0.80798 0.09457
