--------------------------------------------------------------------------------
Note (1): this flag is blank if the object has been detected as a
radio source, and is '*' if not.
Note (2): this flag related to the position takes the values:
'O' for an Optical position with an accuracy better than 1arcsec
'R' for a Radio position with an accuracy better than 1arcsec
'A' for an approximative position
Note (3): the classification of the object is
S1: Seyfert 1 spectrum
S1h: broad polarized Balmer lines detected
S1i: broad Paschen lines observed in the infrared
S1n: narrow-line Seyfert 1
S1.0, S1.2, S1.5, S1.8, S1.9: intermediate Seyfert galaxies
S2: Seyfert 2 spectrum
S3: Seyfert 3 or liner
S : unclassified Seyfert
S?: possibly a Seyfert
H2: nuclear HII region
HP: high optical polarization (>3%)
BL: confirmed BL Lac object
Note (4): n_z may indicate a lower limit on z, or
'*', if the redshift is measured by slitless spectroscopy.
