Abstract:
We present the list of candidate members of the young open cluster
NGC 6611, selected in a field of view of 33'x34' by the X-rays emission
and excesses in infrared bands. X-ray sources without infrared
excesses are classified as candidate Class III cluster members; stars
with infrared excesses as disk bearing members.
Description:
Optical BVI photometry have been obtained from 2.2m WFI@ESO
observations; JHK data are from 2MASS Point Sources Catalog; IRAC
data are from GLIMPSE catalog. X-ray data have been obtained from a
CHANDRA/ACIS-I observation of a field o f 17'x17' centered on the
cluster.

--------------------------------------------------------------------------------
Note (1): Label as follows:
A = the source has infrared excesses and it is candidate to have
a circumstellar disk
A01 = star is classified as a candidate members with disk only by
its position in the IRAC color-color diagram
A10 = infrared excesses are detected only by Q indices
A11 = both diagnostics detect the emission from the disk
B = the star is a X-ray source without infrared excesses, candidate
to be a member without disk
C = the star is a X-ray source without infrared excesses whose
optical colors are compatible with foreground main-sequence stars
Candidate cluster members with infrared excesses are selected in a
field of 33'x34' centered on the cluster;
Candidate cluster members without disk (X-ray sources) are selected in
a field of 17'x17' centered on the cluster
