Align SkyFrames using the offset coordinate system?
If the template and target SkyFrames both have defined offset coordinate systems (i.e. the SkyRefIs
attribute is set to either "
Origin"
or "
Pole"
), and they both have a non-zero value for AlignOffset,
then alignment occurs within the offset coordinate systems (that is, a UnitMap will always be
used to align the two SkyFrames). If either the template or target SkyFrame has zero (the
default value) for AlignOffset, or if either SkyFrame has SkyRefIs set to "
Ignored"
, then
alignment occurring within the coordinate system specified by the AlignSystem attribute.
