OAJ open competitive time is evaluated by the OAJ Time Allocation Committee (OAJ-TAC). The OAJ-TAC consists of a single pannel constituted by 7 members. Two of them will be senior members of CEFCA with a strong scientific background and a good knowledge of the technical capabilities of the OAJ telescopes and cameras. Other members will be selected among senior postdocs and staff astronomers in Spanish institutes, chosen to cover different areas in Astronomy and Astrophysics. The OAJ-TAC is appointed by the Director of CEFCA.

The meetings of the OAJ-TAC will take place at CEFCA well in advance to the beginning of the observing semester under review.
