Spitzer IRAC photometry of M, L, and T dwarfs. Patten B.M., Stauffer J.R., Burrows A., Marengo M., Hora J.L., Luhman K.L., Sonnett S.M., Henry T.J., Raghavan D., Megeath S.T., Liebert J., Fazio G.G. <Astrophys. J., 651, 502-516 (2006)> =2006ApJ...651..502P
ADC_Keywords: Stars, dwarfs ; Stars, late-type ; Photometry, infrared Keywords: infrared: stars - stars: fundamental parameters - stars: late-type - stars: low-mass, brown dwarfs Abstract: We present the results of a program to acquire photometry for 86 late M, L, and T dwarfs using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. We examine the behavior of these cool dwarfs in various color-color and color-magnitude diagrams composed of near-IR and IRAC data. File Summary:

Note (1): Notes as follows: 1 = Source saturated in all four IRAC channels in 30s FRAMETIME data; 2s FRAMETIME data used instead 2 = GTO program PID 33 target; 2s FRAMETIME data 3 = GTO program PID 33 target; 0.6s FRAMETIME data 4 = Channel 1 saturated for 30s FRAMETIME data; used 2s FRAMETIME data for this channel 5 = Channel 2 saturated for 30s FRAMETIME data; used 2s FRAMETIME data for this channel 6 = GTO program PID 33 target 7 = Target source aperture possibly contaminated by flux from another nearby source 8 = Target in crowded field; some contamination of source aperture by other nearby sources possible 9 = Spitzer AOR target name incorrectly reads 2MA 1410+1804 10 = Wings of GJ 1001 PSF may contaminate source aperture for target; however, 2s FRAMETIME data for channels 1 and 2 agree well with the 30s FRAMETIME data 11 = Strong nebulosity in background, especially in channel 4
