Files giving supplemental data for the paper entitled "Final Results from an Adaptive Optics Imaging Survey for Giant Planets Orbiting Nearby Sunlike Stars in the $L'$ and $M$-bands," by A. N. Heinze and P. M. Hinz et al. 2009. PercentileTabs.tar holds plain text files supplying sensitivity vs. radius information in tabular form. These files would be of use to workers trying to duplicate or extend our Monte Carlo simulations to constrain extrasolar planet populations. Each file supplies data for a particular star, and includes two blocks. In the first block, after initial header lines, separations are given in arcseconds followed by ten different sensitivity values in magnitudes for each separation value. These are the 10-sigma, Method 3 sensitivities in the 0th, 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, and 90th data quality percentiles at the given radius. The sensitivities are L' apparent magnitudes, unless the filename appends an 'M' after the star name to indicate M-band magnitudes, as in XiBoMpercenplot06.txt, for example. In the second block of each file the same information is repeated with separations converted to projected AU, and sensitivities converted to Jupiter Masses (MJ). Conversion information and other details are supplied in the paper. PercentilePlots.tar holds .eps plots of the tabular data from the PercentileTabs files. These files will be useful to myself, my coauthors, or other workers in the field of extrasolar planet searches who want figures to illustrate L' or M-band sensitivity, for inclusion in slide presentations or papers. The pp01 plots show all ten percentiles, with sensitivity in magnitudes plotted against separation in arcsec. The pp02 plots show all percentiles, with sensitivity in MJ plotted against separation in projected AU out to 50 AU. The pp03 plots are like pp01 but only the median sensitivity (50th percentile) is shown for simplicity. The pp04 plots are like pp02, but only the median sensitivity is shown. The pp05 plots are like pp02, but the separation axis goes to 100 AU instead of only 50 AU. The pp06 plots are like pp04, but the separation axis goes to 100 AU instead of only 50 AU. SensGrids.tar hold .eps images showing the sensitivity in L' or M-band magnitudes obtained around each star, with a grid of 2x2 arcsec squares superposed for astrometric reference. These plots will be useful to workers preparing to re-observe stars we have studied, or analyzing observations of these stars. For example, if a faint companion is detected at H-band, our sensitivity maps could supply an upper limit in the L' band and thus a constraint on the object's color.
