| | pixel/arcsec | pixel/arcsec is an abbreviation for pixel per arcsecond, which is a unit of angular pixel scale (3600 arcsec = 1 degree). |
| | pixel/deg | pixel/deg is an abbreviation for pixel per degree, which is a unit of angular pixel scale (1 degree = pi/180 radians, so that a full circle comprises 360 degrees). |
| | pixel/radian | pixel/radian is an abbreviation for pixel per radian, which is a unit of angular pixel scale (a full circle comprises 2*pi radians). |
