Notes

A test:

In [1]: import Astronomy as A
In [2]: A.B_epoch_to_J('''00h02m29.056400s''',
                       '''54d11'43.187000"''', 'formatted')
Out[2]: [u'00h05m04.359s', u'+54d28m25.056s']
In [4]: A.J_epoch_to_B('''00h05m04.359s''',
                       '''+54d28'25.056"''', 'formatted')
Out[4]: [u'00h02m29.0564s', u'+54d11m43.1869s']

Seems to be good to about an arcsecond.

:param ra2000 : string

:param dec2000 : string

:param format : string

Returns

tuple of strings
