With the aid of multiwavelength surveys such as the Spitzer legacy programme Surveying the Agents of a Galaxy's Evolution, the Two Micron All Sky Survey and the Magellanic Cloud Photometric Survey, plots have been constructed to expose the relative contributions from molecular hydrogen, polycyclic aromatic hydrocarbons, forbidden emission lines, warm dust continuum and stellar emission at various bands. Besides identifying trends, these plots have helped to reveal PN mimics including six previously known PNe in the outer LMC which are re-classified as other object types. Together with continuing follow-up optical observations, the data have enabled a substantial reduction in the number of PNe previously tagged as 'likely' and 'possible'. The total number of LMC PNe is adjusted to 715 but with a greater degree of confidence in regard to classification. In each colour-colour plot, the more highly evolved LMC PNe are highlighted for comparison with younger, brighter PNe. The faintest and most evolved PNe typically cluster in areas of colour-colour space occupied by ordinary stars. Possible reasons for the wide disparity in infrared colour-colour ratios, such as evolution and dust composition, are presented for evaluation. A correlation is found between the optical luminosity of PNe, emission-line ratios and the MIR dust luminosity at various bands. Luminosity functions using the four Infrared Array Camera and Multiband Imaging Photometer of Spitzer (MIPS) [24] bands are directly compared, revealing an increasing accumulation of PNe within the brightest two magnitudes at longer wavelengths. A correlation is also found between the MIPS [24] band and the [OIII] 5007 and Hβ fluxes. Description: Using the 2MASS 6x catalogue for the LMC (Cutri et al. 2003, Cat. II/246; 2012, Cat. VII/233), magnitudes were obtained for 274 PNe in J, 269 in H and 263 in Ks. To increase the number of detections available for comparison, magnitudes were also obtained from the InfraRed Survey Facility (IRSF) Magellanic Clouds Point Source Catalogue (Kato et al., 2007, Cat. II/288). The 3.6, 4.5, 5.8 and 8um bands were obtained with the IRAC on board Spitzer. This study used the archival data from the Spitzer legacy programme SAGE (Meixner et al., 2006, Cat. J/AJ/132/2268) which mapped the central 7x7deg2 area of the LMC. The MIPS data were also obtained from both the Hora et al. (2008, Cat. J/AJ/135/726) and Gruendl & Chu (2009, Cat. J/ApJS/184/172) studies. File Summary:

Note (G3): (1) refers to analysis using a 2.3m telescope optical spectrum, (2) refers to analysis using follow-up observations on 2dF, 'IR' refers to false infrared colours at 3.6 and 4.5um and 5.8 and 8um indicating HII regions or hot stars, 'Radio' strong radio source (>3mJy).
