The following general subroutines belong to the category PHYSICAL-COORDINATES:
``Calculations with physical coordinates''
In parentheses the name of the source file is given.
AXCOORD
Returns the coordinate type and units as returned by cotrans. (
cotrans.c
)
AXTYPE
The function axtype returns the type of axis, the natural units, secondary units and the projection type. (
axtype.c
)
AXUNIT
Returns the units of the physical coordinates of an axis in a set. (
cotrans.c
)
