Description:
CaII H and K high resolution observations for 60 evolved stars in the
field and in 5 clusters are presented. From these spectra
chromospheric fluxes are derived, and a homogeneous sample of more
than 100 giants is built adding data from the literature. In addition,
for most stars, rotational velocities were derived from CORAVEL
observations.

Global notes:
Note (G1): Flux is given in erg/s/cm2 at the stellar surface.
Note (G2): Binarity flag:
S: single
SB: spectroscopic binary
SBO: spectroscopic binary with known orbit
Note (G3): V/R gives the ratio between the Violet and Red K2 emission in the
line core. V/R<1 may indicate outflows.
