/* ** ** Swift/XRT hardness ratio for M87. ** 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 58872.519298 0.000405 0.18385 0.05241 0.75714 0 3.95190 0.57963 1.94723 0.27548 0.72655 0.17760 0.36234 0.08759 58872.520557 0.000854 0.23318 0.04341 0.67797 0 4.24278 0.40054 1.93245 0.18216 0.98934 0.15875 0.44851 0.07179 58872.521914 0.000498 0.15228 0.04345 0.71512 0 4.23704 0.52146 1.89027 0.23267 0.64521 0.16607 0.28746 0.07395 58872.522834 0.000422 0.22287 0.06296 0.76027 0 3.56817 0.51930 1.60427 0.23339 0.79525 0.19253 0.35463 0.08583 58872.523726 0.000469 0.20823 0.06110 0.69136 0 3.57804 0.55549 1.56492 0.24294 0.74506 0.18551 0.32504 0.08094 58872.525004 0.000810 0.24742 0.04607 0.74286 0 3.99662 0.39437 1.76471 0.17395 0.98884 0.15615 0.43629 0.06894 58872.526353 0.000538 0.12737 0.03398 0.78495 0 4.62149 0.52417 1.99316 0.22582 0.58862 0.14215 0.25651 0.06189 58872.527296 0.000405 0.17833 0.05210 0.74286 0 4.51480 0.62639 1.91209 0.26523 0.80512 0.20701 0.33998 0.08746 58872.528416 0.000715 0.15399 0.03487 0.73022 0 4.54064 0.44064 1.94210 0.18806 0.69919 0.14306 0.29600 0.06044
