Rationale

In section 2.1.1, two RANGE examples display RANGE limits with either Inf or -Inf, + Inf. This is inconsistent with the spec which states that RA is in [0, 360] and DEC in [-90,90] and that no RANGE reduction should be required from SIA services implementations.

Erratum Content

This Erratum proposes following changes.

Fix RANGE syntax

POS=RANGE 0 360.0 89.0 +Inf

to

POS=RANGE 0 360.0 89.0 90.0

and fix the RANGE example for the whole sky

from

POS=RANGE -Inf +Inf -Inf +Inf

to

POS=RANGE 0 360 -90 +90

Impact Assessment

Fixing the RANGE syntax in an example will make no harm to any service and will avoid application implementers writing code requesting incorrect queries.
