Description:
Projected rotational velocities and effective temperatures for 68
delta Sct stars as well as 41 non-variable stars of similar spectral
type and luminosity are presented here. The observations were
performed between 1990 and 1994 at two different observatories: the
Observatorio del Roque de los Muchachos (La Palma, Spain) and the
McDonald Observatory (Texas, USA).

Note (1): Value obtained using the method described in Gray (1992).
For La Palma spectra, the line chosen for the v sin i calculation
appears in the last column (Lambda).
For McDonald spectra, the mean rotational velocity and the standard
deviation are given in the forth column and the number of lines used
is shown in the last column (Line).
The absence of suitable lines prevents the calculation of for VW Ari
and CY Aqr
