/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 56627.262602 0.000382 0.18282 0.01427 0.97727 0 18.59497 0.56403 16.83354 0.51058 3.39953 0.24458 3.07906 0.22153 56627.263432 0.000448 0.15186 0.01161 0.99355 0 18.90388 0.52710 17.04466 0.47524 2.87067 0.20434 2.58989 0.18435 56627.264286 0.000405 0.16734 0.01289 1.00000 0 18.74648 0.55255 17.02996 0.50194 3.13704 0.22330 2.84888 0.20279 56627.265073 0.000382 0.18021 0.01413 1.00000 0 18.44982 0.56553 16.59365 0.50857 3.32486 0.23990 2.99390 0.21596 56627.265822 0.000367 0.18441 0.01450 1.00000 0 18.72125 0.58141 16.94126 0.52615 3.45236 0.24936 3.12896 0.22603 56627.266615 0.000425 0.15244 0.01199 0.99320 0 19.40593 0.54605 17.59073 0.49495 2.95827 0.21718 2.68306 0.19693 56627.267434 0.000394 0.17307 0.01351 0.99265 0 18.59636 0.55499 16.91550 0.50483 3.21845 0.23216 2.92737 0.21116 56627.268227 0.000399 0.16118 0.01254 0.99275 0 19.77646 0.57162 17.99771 0.52021 3.18754 0.23026 2.90057 0.20953 56627.269008 0.000382 0.17665 0.01397 1.00000 0 18.72876 0.57339 16.88261 0.51685 3.30844 0.24127 2.98144 0.21738 56627.269766 0.000376 0.17720 0.01384 1.00000 0 18.94143 0.57467 17.24194 0.52310 3.35641 0.24148 3.05537 0.21983 56627.270501 0.000359 0.17973 0.01425 0.99194 0 19.46557 0.59780 17.71132 0.54392 3.49847 0.25575 3.18331 0.23271 56627.271210 0.000350 0.19386 0.01506 0.99174 0 18.93501 0.59580 17.23142 0.54219 3.67078 0.26063 3.34039 0.23717 56627.271936 0.000376 0.17209 0.01344 0.99231 0 19.56705 0.58446 17.80240 0.53175 3.36729 0.24290 3.06353 0.22098 56627.272671 0.000359 0.18322 0.01444 1.00000 0 19.13149 0.59332 17.40332 0.53972 3.50523 0.25387 3.18850 0.23093 56627.273432 0.000402 0.16415 0.01261 0.97842 0 19.63187 0.56670 17.86469 0.51569 3.22257 0.22939 2.93267 0.20875 56627.274419 0.000584 0.20024 0.01201 0.99505 0 18.86102 0.46066 17.11455 0.41800 3.77670 0.20685 3.42398 0.18752
