Description:
The quality specified by QNAME is removed from all pixels included in (or, if LISTED is
false, not included in) the supplied list of pixel indices. The quality of other pixels is left
unaltered. The quality name must be defined in the NDF specified by LOCS (LOCS should be
obtained either by calling IRQ_FIND or IRQ_NEW). An error is reported if the quality name is
undefined.
Note, write or update access must be available for the NDF (as set up by routine LPG_ASSOC for instance),
and the QUALITY component must not be mapped on entry to this routine.
Invocation
CALL IRQ_RESQL(
LOCS, LISTED, QNAME, NDIM, NCOORD, LIST, SET, STATUS )
Arguments
LOCS(5) = CHARACTER
∗ (
∗
) (Given)
An array of five HDS locators. These locators identify the NDF and the
associated quality name information. They should have been obtained using routine
IRQ_FIND or routine IRQ_NEW.
LISTED = LOGICAL (Given)
If true, then the quality
is removed from all pixels included in the list given by LIST. If false, then the quality is
removed from all pixels not included in the list given by LIST.
QNAME = CHARACTER
∗ (
∗ )
(Given)
The quality name to be removed from the selected pixels. This quality name must be defined
in the NDF specified by LOC. Name definitions can be added to the NDF using routine IRQ_ADDQN.
NDIM = INTEGER (Given)
The number of values required to specify a pixel position (i.e. the
number of dimensions in the NDF).
NCOORD = INTEGER (Given)
The number of pixels included
in the input list.
LIST( NDIM, NCOORD ) = INTEGER (Given)
The list of pixel indices. Any indices
which lie outside the bounds of the NDF are ignored.
SET = INTEGER (Returned)
The number of
pixels which hold the quality.
STATUS = INTEGER (Given and Returned)
The global status.
