call xcc_v_convert( ivector, iepoch, oepoch, isys, osys, ovector )
name & dimensionality | kind | in/out | description |
---|---|---|---|
ivector(1:3) | DP | IN | 3D coordinate vector of one astronomical object, in the input coordinate system. |
iepoch | DP | IN | epoch of the input astronomical coordinate system. |
oepoch | DP | IN | epoch of the output astronomical coordinate system. |
isys(len=*) | CHR | IN | input coordinate system, should be one of 'E'=Ecliptic, 'G'=Galactic, 'C'/'Q'=Celestial/eQuatorial. |
osys(len=*) | CHR | IN | output coordinate system, same choice as above. |
ovector(1:3) | DP | IN | 3D coordinate vector of the same object, in the output coordinate system. |
Will produce in vecout the location in Celestial coordinates (2000 epoch) of the North Galactic Pole (defined in vecin)
