/* ** ** 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 59301.016478 0.000339 0.33639 0.05223 0.98291 0 3.85169 0.30166 2.94605 0.23038 1.29567 0.17369 0.98397 0.13167 59301.017201 0.000385 0.22096 0.03464 0.96241 0 4.49487 0.30390 3.52378 0.23815 0.99317 0.14047 0.78255 0.11067 59301.018017 0.000431 0.18456 0.02922 0.97315 0 4.57858 0.28114 3.68311 0.22616 0.84502 0.12329 0.67967 0.09912 59301.018804 0.000356 0.21455 0.03406 0.95935 0 4.86504 0.32563 3.88126 0.25978 1.04380 0.15026 0.83573 0.12029 59301.019470 0.000310 0.23334 0.03713 0.96262 0 5.17602 0.36011 4.13028 0.28730 1.20775 0.17283 0.96245 0.13771 59301.020092 0.000312 0.25981 0.04165 0.97222 0 4.52991 0.33488 3.65187 0.26995 1.17690 0.16741 0.94904 0.13500 59301.020722 0.000318 0.28456 0.04399 0.99091 0 4.34470 0.31862 3.49088 0.25600 1.23631 0.16826 0.99248 0.13506 59301.021379 0.000339 0.23636 0.03767 0.99145 0 4.50023 0.31393 3.65209 0.25476 1.06366 0.15241 0.86295 0.12365 59301.022308 0.000590 0.25899 0.03039 0.95043 0 4.62159 0.24407 3.69005 0.19486 1.19694 0.12541 0.95791 0.10035
