TRN 34	14 Cep = LZ Cep.
	The image rotator was in an unknown state, so two possible theta
	values are listed for the 2001.7341 observation - one for zenith up
	and one for north up.	Trn2008
	The classification is from Conti & Alschuler (1971). Radial velocity	Cti1971
	and light curve solutions are given by Harries et al. (1998 MNRAS 295,
	386).	Msn1998a

Trn2008		(Note: For some observations the image derotator was in an unknown state. In these
Trn2008		cases the theta value is either left blank or two possible values are listed - one
Trn2008		for zenith up and one for north up. For unresolved objects, the listed rho value
Trn2008		is the FWHM of the corrected stellar PSF. Larger FWHM values are indicative of
Trn2008		poorer seeing and/or non-optimal AO system tuning.)
