Estimated Total Execution Time (hours, including overheads)

5.11 hours (total exposure times from p2pp calcs: 5h 6m 20s)

General Description

Echelle observations of strong CaII H&K QSO absorbers. Main purpose
 is to analysis the velocity structure of said absorbers as well as studying their
 dust content and distribution. This is achieved through observations of ZnII,CrII,FeII,MgII
 and CaII absorption lines in the QSO spectra at S/N >~10 (combined spectra).

This proposal is to complete some targets partially observed in 079.A-0656.  Therefore
 total S/N constraints quoted include adding exposures from that semester.

Finding charts quote program 079.A-0656 in the top corner as they have not changed
 from that program, but they are suitable for the objects in this run.
