IRA_READ

Gets an identifier for astrometry information stored in an HDS astrometry structure

Description:

An attempt is made to read astrometry information from the supplied HDS object, assuming the object is an IRA astrometry structure. The astrometry information is copied into internal common blocks and an " IRA identifier" is returned which can be passed to other IRA routines to refer to the stored astrometry information. This identifier should be annulled when it is no longer required by calling IRA_ANNUL.

Invocation

CALL IRA_READ( LOC, IDA, STATUS )

Arguments

LOC = CHARACTER ∗ ( ∗ ) (Given)
An HDS locator to an astrometry structure. The constant IRA__HDSTY gives the HDS type required for this object.
IDA = INTEGER (Returned)
The IRA identifier which is used by other IRA routines to access the astrometry information.
STATUS = INTEGER (Given and Returned)
The global status.
