[vsnet-chat 853] A question

[Gianluca Masi <gianmasi@fr.flashnet.it>]

Dear Friends,
I would like to know your opinion about what follows. As you know, there
are two main ways to do astronomical photometry, using a CCD camera:
aperture and PSF photometry. I was wondering which is the best one when
the telescope used to capture the star light has a short focal lenght (1
meter, for example), with a typical FHWM of 1.5-2.0 pixels. PSF fitting
maybe difficult, considering such a small FWHM.

Have you any consideration on this point? 

Thank you for the attention and best regards.

Gianluca
