An analysis of 2MASS near-infrared photometry for galactic planetary nebulae. Larios G.R., Phillips J.P. <Mon. Not. R. Astron. Soc., 357, 732-752 (2005)> =2005MNRAS.357..732L
ADC_Keywords: Surveys ; Planetary nebulae ; Infrared sources Keywords: surveys - planetary nebulae: general - infrared: ISM Abstract: The recently published 2MASS all-sky infrared survey (II/246) includes JHKs photometry of over 300 million sources. It also provides sizes and aspect ratios for the ∼0.55 per cent of objects that appear in the extended-source catalogue. Although most of these detections correspond to galaxies, stars, H II regions, young stellar objects, reflection nebulae and so forth, a number of them also appear to correspond to galactic planetary nebulae (PNe). We have used this survey to determine the near-infrared properties of some 325 known galactic PNe. File Summary:

Note (1): Remarks as follows: 1 = Source appears extended in 2MASS imaging, but is not contained in the Extended Source Catalogue 2 = Possible weak contamination of fluxes by field star(s) 3 = Extended nebular emission is observed but weak, and fluxes are dominated by the central star 4 = Possible strong contamination of fluxes by field star(s) 5 = Possibility of source confusion 6 = Fluxes may be contaminated by bright star diffraction pattern 7 = The size in the 2MASS Extended Source Catalogue appears too great, and may be affected by the high density of field stars 8 = Source weak, only partially detected; 2MASS sizes may be in error
