The CLASS commands dealing with the position of the spectrum are not
affected by the renaming of the coordinate system, nor by the
reordering of the variables. On the other hand, several commands are
added or improved to fully benefit the new projection kinds and
possible non-zero angle.
- MODIFY PROJECTION is added. It allows to modify the
current R spectrum projection, including setting a new projection
and a non-zero angle. It uses the GREG reprojection engines from
any projection to another.
- MODIFY POSITION is now a shortcut for MODIFY
PROJECTION, in the particular case when the projection system and
angle are left unchanged. Thanks to this, it supports now any kind
of projection.
- CONSISTENCY now checks in details the projection of all
observations in index, i.e. the projection systems, centers, and
angles.
- TABLE benefits the CONSISTENCY improvements, in both
NEW or OLD modes. In the latter case, TABLE
verifies that the appended spectra have a projection consistent with
the old ones. The projection description of the spectra (including
their angle) is saved in the table header.
- XY_MAP benefits the TABLE improvements, including
the possible non-zero projection angle in the table header.
