摘要：
A spatial template is important to study nearby supernova remnants(SNRs). For SNR G332.5-5.6, we report a Gaussian disk with a radius of about 1°.06 to be a potential good spatial model in the γ-ray band. Employing this new Gaussian disk, its GeV lightcurve shows a significant variability of about seven sigma. The γ-ray observations of this SNR could be explained well either by a leptonic model or a hadronic model, in which a flat spectrum for the ejected electrons/protons is required.
