/* ** ** 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 54954.366573 0.000518 0.44633 0.07672 0.96089 0 4.26785 0.40674 1.29362 0.12328 1.90487 0.27251 0.57636 0.08247 54954.367794 0.000703 0.29399 0.04733 0.96296 0 4.86264 0.37410 1.45323 0.11180 1.42958 0.20218 0.42806 0.06054 54954.368827 0.000330 0.25443 0.06395 0.96491 0 4.75711 0.54613 1.43294 0.16451 1.21034 0.27064 0.36424 0.08145 54954.369467 0.000310 0.25285 0.06310 0.99065 0 5.21168 0.60144 1.55231 0.17910 1.31778 0.29161 0.39202 0.08674 54954.370320 0.000544 0.31545 0.05219 0.97340 0 5.69376 0.46451 1.70754 0.13930 1.79607 0.25854 0.53890 0.07756 54954.371403 0.000538 0.37480 0.06312 0.96774 0 4.92160 0.43702 1.46776 0.13033 1.84464 0.26395 0.55075 0.07880 54954.372534 0.000593 0.39611 0.06742 0.96098 0 4.22577 0.38397 1.26380 0.11483 1.67385 0.24090 0.50060 0.07205 54954.373521 0.000394 0.28170 0.06335 0.96324 0 4.64814 0.49314 1.39142 0.14761 1.30939 0.25963 0.39367 0.07808 54954.374597 0.000683 0.23163 0.03699 0.96610 0 6.27856 0.43412 1.86647 0.12904 1.45428 0.20933 0.43253 0.06225 54954.375636 0.000356 0.27304 0.06606 0.98374 0 4.66984 0.52254 1.39191 0.15575 1.27508 0.27351 0.38029 0.08156 54954.376362 0.000370 0.19927 0.04957 0.94531 0 5.54644 0.56500 1.63807 0.16683 1.10522 0.25083 0.32686 0.07417 54954.377172 0.000440 0.34394 0.06860 0.94737 0 4.60307 0.46856 1.37927 0.14037 1.58317 0.27153 0.47301 0.08112
