Next: The APM selected sample Up: Second priority candidates Previous: Second priority candidates . From the random selected subsample of second priority candidates we observed twenty six objects during the 6-m telescope runs (mainly those with R.A.< 11 h ) along with the observations of first priority targets. Altogether we found 12 emission-line objects: one appeared to be a QSO with z =3.15, and the rest are various types of ELGs. ... One object is an absorption-line galaxy. ...

... The first step to improve the FORS calibration is therefore to obtain data to allow a computation of the illumination correction across the field. ... Another limitation on the calibration accuracy has been the brightness of the Landolt standards which have forced the use of extremely short exposures introducing small but non-negligible shutter-time errors and also resulting in a very small number of useful standards per frame. ...

The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

... The three optical trains for the cameras, and the pupil reimaging system, are mounted on a wheel, accurately driven by an external motor. ... The low-resolution spectroscopic mode uses the wide field camera and a suitable set of grisms and order sorting filters that are inserted in the parallel beam after the pupil. ... One of the five grisms can operate at four different orders, depending on the filter selected on the first filter wheel that acts as order sorter. ...
