/* ** ** Swift/XRT hardness ratio for B2 1811+31. ** 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 53677.004843 0.001380 0.19386 0.07057 0.98364 1 0.40775 0.05962 0.20173 0.02949 0.07905 0.02635 0.03852 0.01284 53690.003753 0.000315 0.03422 0.03937 0.98118 0 0.63897 0.12589 0.48468 0.09549 0.02186 0.02479 0.01663 0.01885 53691.004515 0.001002 0.28063 0.07731 0.99893 1 0.42750 0.05585 0.35105 0.04586 0.11997 0.02910 0.09865 0.02393 59125.513804 0.068061 0.14175 0.01423 0.20556 1 0.57491 0.02020 0.35859 0.01219 0.08149 0.00766 0.05015 0.00457 59128.622860 0.335472 0.13931 0.02255 0.02181 1 0.31262 0.01778 0.24935 0.01418 0.04355 0.00660 0.03477 0.00527 59132.358743 0.068321 0.12485 0.02306 0.09459 1 0.29747 0.01829 0.23716 0.01457 0.03714 0.00647 0.02967 0.00516 59134.869701 0.012972 0.13490 0.01894 0.65502 1 0.64116 0.03103 0.29571 0.01429 0.08649 0.01140 0.03959 0.00521 59136.890871 0.038941 0.17600 0.02101 0.29261 1 0.68224 0.03227 0.25570 0.01152 0.12007 0.01316 0.04666 0.00489 59138.894164 0.039132 0.18857 0.01774 0.26780 1 0.50119 0.01882 0.39499 0.01482 0.09451 0.00815 0.07473 0.00644 59156.865490 0.034748 0.21250 0.01776 0.31995 1 1.71283 0.06011 0.42997 0.01509 0.36397 0.02761 0.09145 0.00694 59157.860856 0.034091 0.18851 0.02094 0.30661 1 0.71652 0.03168 0.28906 0.01271 0.13507 0.01376 0.05427 0.00550
