Simple spectroscopic program aiming at determining the correlation between O and Be abundances in galactic stars at the halo-disk transition, already known to have different O contents. Objects have different priorities (#1) as specified in README file. For some targets, exposure times longer than 1h have been used, under the agreement that OBs will not be repeated should the atmospheric conditions degrade during the time exceeding the first hour. Authorized change of target (CD -33 1173 to replace G46-31). Requirements: ONE telluric standard star needs to be observed on each night one or more Dic1_346+580 OBs are executed. See README file for exact association target--telluric star. 8 such OBs have been prepared, although there are 10 Dic1 OBs in the need of such calibration star. If possible, the 2 Dic1 OBs for targets G5-40 and CD -33 1173 should be observed on the same night. However, it is important that at least one of the 2 Dic1 OBs of these 2 stars is executed together with its corresponding telluric standard star.
