measures.toradialvelocity - Function

1.3.1 convert a doppler type value to a real radial velocity
Description

toradialvelocity will convert a Doppler type value (e.g. in radio mode) to a real radialvelocity. The type of velocity (e.g. LSRK) should be specified

Arguments


Inputs
rf	radial velocity reference type
	allowed:	string
	Default:
v0	doppler value measure
	allowed:	any
	Default:	record

Returns
anyrecord

Example

print "\t----\t toradialvelocity Ex 1 \t----"
a = me.doppler(’radio’,’0.4’)
print a
# Out[4]:
#{’m0’: {’value’: 119916983.2, ’unit’: ’m/s’},
# ’refer’: ’RADIO’,
# ’type’: ’doppler’}
print me.toradialvelocity(’topo’,a)
#{’m0’: {’value’: 141078803.7647059, ’unit’: ’m/s’},
# ’refer’: ’TOPO’,
# ’type’: ’radialvelocity’}
