/* ** ** 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 56463.227122 0.000764 0.49264 0.13792 0.96212 0 0.42354 0.06978 0.31559 0.05199 0.20865 0.04723 0.15593 0.03530 56463.228503 0.000616 0.62631 0.18045 0.92958 0 0.43490 0.07900 0.32048 0.05820 0.27238 0.06091 0.20236 0.04525 56463.229784 0.000666 0.50843 0.14014 0.95217 0 0.48292 0.07781 0.35958 0.05794 0.24553 0.05490 0.18295 0.04091 56463.231205 0.000755 0.73137 0.17997 0.95453 0 0.42646 0.06847 0.31830 0.05110 0.31190 0.05817 0.23227 0.04331 56463.629102 0.000799 0.51165 0.14182 0.95652 0 0.39070 0.06330 0.29490 0.04778 0.19990 0.04496 0.15095 0.03395 56463.630399 0.000498 0.80905 0.24497 0.97093 0 0.39311 0.08025 0.29497 0.06021 0.31804 0.07112 0.23992 0.05365 56463.631787 0.000891 0.57502 0.16225 0.98052 0 0.30535 0.05254 0.23094 0.03974 0.17558 0.03926 0.13267 0.02967 56463.633466 0.000787 0.48572 0.13349 0.97426 0 0.41329 0.06527 0.31019 0.04899 0.20074 0.04515 0.15038 0.03382 56463.634915 0.000663 0.43342 0.11645 0.96943 0 0.55458 0.08259 0.41683 0.06207 0.24037 0.05375 0.18048 0.04036 56463.636191 0.000613 0.47348 0.12988 0.98113 0 0.53565 0.08412 0.40447 0.06352 0.25362 0.05704 0.19159 0.04309 56463.637502 0.000697 0.43875 0.12070 0.97510 0 0.50155 0.07660 0.38019 0.05807 0.22005 0.05035 0.16681 0.03817 56463.638891 0.000692 0.59109 0.15696 0.98326 0 0.43955 0.07227 0.33091 0.05440 0.25981 0.05418 0.19607 0.04088
