PHYSICAL-COORDINATES general subroutines

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)

COTRANS

Transformation from grid coordinates to physical coordinates and vice versa. (cotrans.c)

DRAWAXIS

Label an axis with (transformed) coordinates (drawaxis.c)

factor

Factor returns the conversion factor between two different units (i.e. M en KM) (factor.c)

GDSBOX

GDSBOX prompts the user to define a box inside/around a subset. (gdsbox.c)

GDSPOS

GDSPOS prompts the user to define a position in a subset. (gdspos.c)

GETPRO

Returns the type of sky projection of a subset. (cotrans.c)

GETROT

Returns the rotation angle of a subset. (cotrans.c)

GETSKY

Returns the type of sky system of a subset. (cotrans.c)

GRTOPH

Transformation from grid coordinates to physical coordinates in a subset. (cotrans.c)

NCOORDS

Returns the number of coordinates returned by COTRANS. (Including the hidden coordinates.) (cotrans.c)

PHTOGR

Transformation from pysical coordinates to grid coordinates in a subset. (cotrans.c)

SKYROT

Returns the rotation angle of the sky in a set. (cotrans.c)

units

Units returns the type of units. (factor.c)
