Standard stellar spectroscopy of 7 stars in NGC6528. The total exposure time of each target is split in 2 or 3 OBs (named a,b, and c) of 1h20min/1h30min each. The field is very crowded, but positions have been derived from HST images (claimed accuracy better than 1"). Finding charts have been smoothed to mimic a seeing of 1.2", which is the constraint of the program. In one case (OB: NGC6528-03a,b,c) two, well separated, stars fall simultaneously on the slit. Should problems arise in placing the 2nd star on the slit after offset has been applied, please go ahead with 1st target only. One telluric standard star (8 OBs: NGC6528B-01,..08) has been provided to be observed on each night science targets of the program are observed. P.I. is aware that these "telluric star" OBs may not be sufficient to cover all nights of observations (preferentially, science targets should be grouped together).
