/* ** ** 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 55783.490046 0.000321 0.25330 0.04062 0.98198 0 4.17919 0.30168 3.58659 0.25891 1.05858 0.15157 0.90900 0.13015 55783.490708 0.000341 0.29216 0.04745 0.96610 0 3.50074 0.26823 2.97415 0.22785 1.02279 0.14647 0.86913 0.12444 55783.491394 0.000344 0.27676 0.04471 0.95797 0 3.70310 0.27728 3.14221 0.23530 1.02488 0.14672 0.86914 0.12444 55783.492546 0.000807 0.29335 0.02894 0.97846 0 3.97666 0.18705 3.36217 0.15814 1.16654 0.10118 0.98809 0.08570 55783.493671 0.000318 0.31051 0.05018 0.97273 0 3.55244 0.27762 3.02261 0.23619 1.10308 0.15601 0.93614 0.13239 55783.494337 0.000347 0.30913 0.05025 0.96667 0 3.29016 0.25855 2.77827 0.21832 1.01709 0.14472 0.85883 0.12221 55783.495066 0.000382 0.24278 0.03877 0.97727 0 3.70665 0.26229 3.16312 0.22382 0.89989 0.12884 0.76807 0.10997 55783.496377 0.000929 0.34022 0.03151 0.98754 0 3.48003 0.16322 2.92683 0.13726 1.18397 0.09457 0.99508 0.07947 55783.497956 0.000651 0.31787 0.03513 0.99111 0 3.65000 0.19810 3.10440 0.16847 1.16022 0.11168 0.98500 0.09480 55783.499502 0.000894 0.30190 0.02821 0.98706 0 3.86699 0.17470 3.28014 0.14818 1.16743 0.09548 0.99126 0.08106 55783.501565 0.001169 0.33340 0.02712 0.97030 0 3.66871 0.14895 3.11981 0.12665 1.22316 0.08620 1.03935 0.07325
