Fillers and variables
The standard CLASS fillers reflect the changes in the Position
section. At the Fortran level, the type(observation) is modified
as follows:
- obs%head%pos%projang (angle in radians) is added,
- obs%head%pos%system replaces obs%head%gen%typec. Its value remains the special GILDAS code for coordinate systems. Note that obs%head%gen%typec
was a convenient duplicate in memory of the corresponding index
element, so this affects only the General section in memory, not on
disk.
- obs%head%pos%sl0p, obs%head%pos%sb0p and obs%head%pos%sk0p are removed.
At the end-user level, the following SIC variables are affected:
- R%HEAD%POS%PROJANG is added,
- R%HEAD%POS%SYSTEM replaces R%HEAD%GEN%TYPEC
and TYPEC which are removed,
- R%HEAD%POS%SL0P, R%HEAD%POS%SB0P and R%HEAD%POS%SK0P are removed,
Finally, for Python-based fillers, the attributes are changed in the
same way:
- obs.head.pos.projang is added,
- obs.head.pos.system replaces obs.head.gen.typec,
- obs.head.pos.sl0p, obs.head.pos.sb0p and obs.head.pos.sk0p are removed.
