/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 59133.812876 0.001177 0.60457 0.17155 1.00000 1 0.19941 0.03483 0.16245 0.02837 0.12056 0.02696 0.09877 0.02208 59133.815941 0.001888 0.63447 0.18316 0.99231 1 0.11884 0.02170 0.09756 0.01781 0.07540 0.01686 0.06202 0.01387 59133.819239 0.001409 0.89711 0.27799 0.98969 1 0.11263 0.02401 0.09263 0.01975 0.10104 0.02272 0.08290 0.01864 59133.821868 0.001220 1.29219 0.42881 0.96429 1 0.09739 0.02435 0.08000 0.02000 0.12584 0.02746 0.10370 0.02263 59133.824511 0.001423 0.66572 0.19346 0.95918 1 0.15359 0.02804 0.12632 0.02306 0.10225 0.02312 0.08422 0.01904 59133.827533 0.001598 0.48624 0.12975 0.96364 1 0.19809 0.03009 0.16181 0.02458 0.09632 0.02113 0.07885 0.01730 59133.831251 0.002121 0.51074 0.12691 0.99450 1 0.16455 0.02426 0.13510 0.01992 0.08404 0.01681 0.06887 0.01377 59133.878788 0.001206 0.98786 0.31110 0.95181 1 0.12548 0.02767 0.10143 0.02237 0.12396 0.02787 0.10074 0.02265 59133.881504 0.001511 0.56896 0.15659 0.98077 1 0.17920 0.03005 0.14462 0.02425 0.10196 0.02225 0.08235 0.01797 59133.886632 0.003617 0.44456 0.09200 0.99147 1 0.15466 0.01791 0.12414 0.01438 0.06876 0.01179 0.05509 0.00945
