/* ** ** 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 54915.155529 0.000515 0.21752 0.03394 0.98315 0 4.05254 0.27045 2.68192 0.17785 0.88150 0.12432 0.58383 0.08175 54915.156498 0.000454 0.19870 0.03132 0.98089 0 4.42472 0.28396 3.21754 0.20649 0.87921 0.12658 0.64023 0.09217 54915.157398 0.000446 0.21568 0.03366 0.97403 0 4.26604 0.28158 3.09287 0.20414 0.92010 0.13013 0.66778 0.09444 54915.158174 0.000330 0.29164 0.04740 0.97368 0 4.20692 0.32416 3.07595 0.23698 1.22690 0.17559 0.89296 0.12779 54915.158885 0.000382 0.23560 0.03760 0.99242 0 4.46288 0.31526 3.20221 0.22620 1.05144 0.15049 0.75663 0.10828 54915.159664 0.000396 0.24771 0.03908 0.94891 0 4.29716 0.30046 3.11150 0.21755 1.06447 0.15054 0.77051 0.10897 54915.160529 0.000469 0.18500 0.02857 0.98148 0 4.70767 0.29187 3.40418 0.21107 0.87094 0.12317 0.62998 0.08909 54915.161380 0.000382 0.22663 0.03564 0.94697 0 4.86093 0.32548 3.51667 0.23546 1.10161 0.15673 0.79714 0.11340 54915.162207 0.000446 0.21023 0.03355 0.98701 0 4.23537 0.28364 3.07081 0.20565 0.89041 0.12898 0.64520 0.09345 54915.163023 0.000370 0.27606 0.04446 0.99219 0 3.96469 0.29923 2.84796 0.21494 1.09449 0.15570 0.78459 0.11162 54915.163787 0.000394 0.22817 0.03609 0.97794 0 4.54351 0.31395 3.29239 0.22746 1.03670 0.14748 0.74919 0.10658 54915.164583 0.000402 0.26743 0.04233 0.94964 0 4.07208 0.29224 2.90756 0.20868 1.08900 0.15364 0.77728 0.10966 54915.165509 0.000524 0.19180 0.02976 0.95580 0 4.13728 0.25600 2.99461 0.18528 0.79353 0.11289 0.57597 0.08194 54915.166440 0.000408 0.21028 0.03308 0.95745 0 4.85969 0.31719 3.49982 0.22840 1.02188 0.14627 0.73421 0.10507 54915.167355 0.000506 0.19415 0.02970 0.95429 0 4.40102 0.26850 3.18245 0.19414 0.85447 0.11989 0.61752 0.08662 54915.168217 0.000356 0.26641 0.04298 0.96748 0 4.28208 0.31908 3.12375 0.23276 1.14079 0.16325 0.83293 0.11920 54915.169018 0.000446 0.20945 0.03252 0.95455 0 4.52743 0.28767 3.28188 0.20852 0.94825 0.13433 0.68791 0.09745 54915.170132 0.000668 0.19758 0.02533 0.97403 0 4.57791 0.23819 3.31205 0.17231 0.90451 0.10600 0.65422 0.07666
