Title - Frame title

Description:

This attribute holds a string that is used as a title in (e.g.) graphical output to describe the co-ordinate system that a Frame represents. Examples might be "Detector Co-ordinates" or "Galactic Co-ordinates".

If a Title value has not been set for a Frame, then a suitable default is supplied.

The default supplied by the Frame class is "<n>-d co-ordinate system", where <n> is the number of Frame axes (Naxes  attribute).

Specialised Frames (SkyFrame, SpecFrame, etc.) re-define the default Title value to be appropriate to the particular co-ordinate system being represented.

Type:

String.

Examples:

wcsattrib my_data set Title "My own data"

This sets the Title for the current Frame in the NDF called my_data, to the string "My own data".

Notes:

• A Frame's Title is intended purely for interpretation by human readers and not by software.
