Dear Frinds 
i have this code 
from astroquery.simbad import Simbad

def get_star_info(star_name):
    custom_simbad = Simbad()
    custom_simbad.add_votable_fields('ra(epoch=J2000)', 'dec(epoch=J2000)','ra(epoch=FK4)', 'dec(epoch=FK4)', 'ra(epoch=B1950)', 'dec(epoch=B1950)', 'pmra', 'pmdec', 'rv_value', 'plx', 'flux(V)', 'flux(B)')
    result_table = custom_simbad.query_object(star_name)
    if result_table is not None:
        ra_j2000 = result_table['RA_epoch_J2000'][0]

        apparent_magnitude_V = result_table['FLUX_V'][0]
        apparent_magnitude_B = result_table['FLUX_B'][0]
       
        # Calculate absolute magnitude
        absolute_magnitude = apparent_magnitude_V - 5 * (1 + 0.2) * (parallax / 1000)
       
        # Calculate distance in parsecs
        distance_parsecs = 1 / (parallax / 1000)
       
        # Calculate distance in light-years
        distance_ly = distance_parsecs * 3.26
       
        info = {
            "RA_J2000": ra_j2000,

        }
        return info
    else:
        return None

# Example star names

        print()
    else:
        print(f"Star: {star_name} not found in SIMBAD database.")


and in result Ra and Dec of 1950  is equal Ra dec of 2000
i want to take hd and hip and tyc number and bayer code of this stars in output and i dont know how can i do that
