/* ** ** 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 57678.146471 0.000376 0.21270 0.03305 1.00000 0 4.27756 0.28027 3.66971 0.24045 0.90985 0.12818 0.78177 0.11013 57678.147267 0.000420 0.25431 0.04045 0.97931 0 3.25714 0.23524 2.79763 0.20204 0.82832 0.11739 0.71189 0.10090 57678.148045 0.000359 0.23690 0.03743 0.99194 0 4.04411 0.28473 3.43509 0.24185 0.95806 0.13550 0.81436 0.11517 57678.148806 0.000402 0.23587 0.03724 0.98561 0 3.67449 0.25773 3.09518 0.21706 0.86669 0.12258 0.73114 0.10340 57678.149718 0.000509 0.16546 0.02543 0.98295 0 4.07681 0.23670 3.48282 0.20219 0.67453 0.09600 0.57587 0.08194 57678.150618 0.000391 0.20960 0.03302 0.97778 0 4.26445 0.28015 3.57811 0.23506 0.89381 0.12798 0.75065 0.10747 57678.151462 0.000454 0.19405 0.02997 0.98726 0 3.96525 0.25091 3.36630 0.21302 0.76944 0.10840 0.65568 0.09237 57678.152467 0.000550 0.16347 0.02510 0.96842 0 3.90790 0.22530 3.31311 0.19100 0.63881 0.09090 0.54145 0.07704 57678.153384 0.000367 0.22010 0.03449 0.96850 0 4.35001 0.29336 3.69390 0.24908 0.95745 0.13541 0.81436 0.11517 57678.154116 0.000365 0.23174 0.03658 0.96825 0 4.17160 0.28501 3.52251 0.24061 0.96672 0.13758 0.81661 0.11620 57678.154993 0.000512 0.17296 0.02665 0.95480 0 4.04247 0.23898 3.40213 0.20113 0.69918 0.09949 0.58950 0.08388 57678.156026 0.000521 0.15117 0.02314 0.97778 0 4.51193 0.25095 3.78154 0.21032 0.68207 0.09727 0.57130 0.08146 57678.157102 0.000556 0.14997 0.02292 0.98958 0 4.11253 0.22921 3.50161 0.19517 0.61676 0.08776 0.52435 0.07461 57678.158155 0.000498 0.19988 0.03110 0.94767 0 3.57230 0.22501 3.06005 0.19272 0.71404 0.10160 0.61120 0.08697 57678.159136 0.000483 0.18456 0.02861 0.98802 0 3.83728 0.23559 3.26643 0.20054 0.70821 0.10079 0.60380 0.08592 57678.160163 0.000544 0.15654 0.02426 0.97340 0 4.04005 0.23099 3.44094 0.19674 0.63244 0.09111 0.53850 0.07758 57678.161240 0.000532 0.20092 0.02947 0.98370 0 3.77058 0.22482 3.22698 0.19240 0.75759 0.10154 0.64828 0.08691
