Package gavo :: Package stc :: Module conform

Module conform

"Conforming" of STCSpecs, i.e., bringing one to the system and units of the other.

You can only conform STCSpecs rather than individual components, since usually you need the whole information for the transformation (e.g., space and time for velocities.

Classes
	SphercLoader A hack to delay loading of spherc.

Functions

iterSpatialChanges(baseSTC, sysSTC, slaComp=False)
yields changes to baseSTC to bring places and velocities to the system and units of sysSTC.

source code

iterTemporalChanges(baseSTC, sysSTC)

source code

conformUnits(baseSTC, sysSTC)
returns baseSTC in the units of sysSTC.

source code

conformSystems(baseSTC, sysSTC, relativistic=False, slaComp=False)
conforms places and velocities in fromSTC with toSTC including precession and reference frame fixing.

source code

conform(baseSTC, sysSTC, **kwargs)
returns baseSTC in the units and the system of sysSTC.

source code

getSimple2Converter(srcSTC, destSTC, slaComp=True)
returns a function that transforms lat and long in srcSTC to lat and long in destSTC.

source code

Variables
	spherc = `<gavo.stc.conform.SphercLoader object>`
	i = `[0]`
	__package__ = `'gavo.stc'`

Function Details

iterSpatialChanges(baseSTC, sysSTC, slaComp=False)

source code

yields changes to baseSTC to bring places and velocities to the system and units of sysSTC.

sixTrans is a sphermath.SVConverter instance.

If the frame or units are not defined in sysSTC, there are taken from baseSTC.

getSimple2Converter(srcSTC, destSTC, slaComp=True)

source code

returns a function that transforms lat and long in srcSTC to lat and long in destSTC.

srcSTC and destSTC are ASTs. Of course, all this only works if srcSTC and destSTC are both SPHER2-flavored.
