irfpy.vexpvat.pvat

VEX pvat information.

Warning

This module is deprecated. Use irfpy.vexpvat.vexspice module.

PVAT information is obtained from Peje’s format file. The simplest way is using getPvatFile() to instance PvatFile class.

>>> pv = getPvatFile(1500)    
>>> print(pv.poslist.firstJd())    
 2455346.25200(2010-05-29T18:02:52.800)
>>> print(pv.poslist.lastJd())    
 2455347.25270(2010-05-30T18:03:53.280)

>>> pv2 = getPvatFile(1501)    
>>> print(pv2.poslist.firstJd())
