Gauss curve produced by Astrometrica. The total PSF is using the aperture circle of 5 x 5 pixel around the brightest pixel.
You see the Gauss curve right as the computed ideal line and the real pixels contributed around the ideal line.
The Fit RMS is the deviation from the ideal line (inlay under the Gauss curve).


Photometry computed with FOCAS II, using the Multibox method:

FoCAs II - 07/01/2009-b

FOCAS II is a tool for photometry on the base of data coming from Astrometrica. Focas is basically using the .LOG file of Astrometrica.

Explanation of the FOCAS II table headings:

Object, date and time are self-explaining.
10x10, 20x20 ... 60x60 are the measured magnitudes according to the aperture sizes of photometry in arc sec (rectancle).
SNR is the  Signal-to-noise ratio for aperture photometry (calculator).
SB is the magnitude of the faintest star on the image matching with the used star catalogue. This is not the faintest star of the image!
COD is the MPC Code of the observatory.

second line:
+/- are the precisions of the measurements.
N is the number of the used images for the measurements.
FWHM is the Full-Width Half-Maximum of the total PSF: Measure of the seeing.
CAT is the used star catalog in Astrometrica.
