/* ** ** 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 56871.916300 0.000388 0.37646 0.03146 0.99254 0 8.80589 0.38539 7.96055 0.34841 3.31511 0.23600 2.99865 0.21347 56871.917070 0.000382 0.33323 0.02772 1.00000 0 9.98286 0.41635 9.03341 0.37666 3.32655 0.23944 3.00856 0.21653 56871.917857 0.000405 0.32524 0.02650 0.98571 0 9.79650 0.39644 8.92696 0.36125 3.18619 0.22530 2.90338 0.20530 56871.918690 0.000428 0.32806 0.02821 1.00000 0 8.75976 0.36839 7.94222 0.33396 2.87377 0.21550 2.60844 0.19552 56871.919509 0.000391 0.31445 0.02583 0.98519 0 10.46252 0.41992 9.48782 0.38081 3.28994 0.23578 2.98476 0.21392 56871.920313 0.000414 0.33434 0.02828 0.99301 0 9.04737 0.38433 8.24481 0.35024 3.02485 0.22125 2.75657 0.20163 56871.921121 0.000394 0.33215 0.02833 0.98529 0 9.56782 0.40314 8.71220 0.36708 3.17798 0.23564 2.89358 0.21455 56871.921876 0.000362 0.39092 0.03328 0.99200 0 9.08363 0.41061 8.15395 0.36864 3.55096 0.25619 3.18651 0.22993 56871.922622 0.000385 0.36098 0.03034 0.98496 0 9.16953 0.39517 8.35553 0.36009 3.30999 0.23884 3.01624 0.21764 56871.923378 0.000370 0.36756 0.03125 0.97656 0 9.39861 0.41056 8.56323 0.37407 3.45455 0.25201 3.14749 0.22961 56871.924156 0.000408 0.32479 0.02694 0.98582 0 9.60417 0.39282 8.75208 0.35797 3.11933 0.22508 2.84264 0.20512 56871.924981 0.000417 0.36401 0.03059 0.99306 0 8.40306 0.36890 7.62350 0.33469 3.05879 0.21923 2.77604 0.19896 56871.925776 0.000379 0.35740 0.03040 0.98473 0 9.31819 0.40458 8.49010 0.36862 3.33030 0.24359 3.03437 0.22194 56871.926555 0.000399 0.33761 0.02874 1.00000 0 9.22751 0.39244 8.40840 0.35760 3.11528 0.22973 2.83874 0.20934 56871.927362 0.000408 0.35913 0.02929 0.98582 0 9.16636 0.38509 8.35365 0.35095 3.29189 0.23010 3.00005 0.20970
