%6.2f
Pixel
Horizontal coordinate, in pixels, of the comet centroid as measured in the source FITS image. This value assumes 1) the image is displayed with lines increasing up and samples or rows to the right and 2) the value (0,0) is located at the center of the bottom left pixel.

%6.2f
Pixel
Vertical coordinate, in pixels, of the comet centroid as measured in the source FITS image. This value assumes 1) the image is displayed with lines increasing up and samples or rows to the right and 2) the value (0,0) is located at the center of the bottom left pixel.

%7.2f
Pixel
Distance, in pixels or columns, of comet centroid from horizontal boundary between CCD quadrants. For a 512x512 pixel image, this boundary is defined as X column 255.5 assuming (0,0) is located at the center of the bottom left pixel.

Image_Quality
11
103
ASCII_Integer
1
%1d
Quality flag manually assigned to the source FITS image. The possible values are: 0 = Good 1 = Star located within a 9-pixel radius of the centroid, possibly affecting small-aperture photometry 2 = Cosmic ray located within a 9-pixel radius of the centroid, possibly affecting small-aperture photometry. Images of poor quality, such as those that were saturated or corrupt are not included in this photometry table.
