General Description

This program aims at fully characterize and calibrate the NB filter ESO#865,
 centered on the Ca H+K lines. This is a preliminary step towards the execution of
 a pure photometric survey for the detection of metal poor stars ([Fe/H]<-3.0)
 in the galactic halo. In fact, this filter used in combination with SDSS ugriz photometry
 will allow to have a photometric determination of stars metallicity.
However, the full use of filter ESO#865 is completely hampered by lack of a proper
 photometric calibration. 

We therefore will observe a 1square degree field on SDSS field and a large sample
 of slocan standards. Primary star will be BD+174708 since it is one of the 3 spectro-photometric
 standards of SDSS and HST/ACS.

Observations should be performed under photometric conditions.

All standards are taken from Smith et al. 2002, AJ, 123, 2121
