The GIPSY coordinate system is implemented in terms of a collection of mostly FITS-compatible GDS descriptor items. ... The axis name is uniquely related to the physical coordinates of the pixels along the axis. ... For this position the physical coordinate is precisely defined in CRVAL i , and therefore we call this position the projection centre. ... The GIPSY coordinate system also recognizes secondary axis descriptors, which relate grid positions to a different type of physical units. ...
