Observations were performed between August 1995 and March 1996 at 4.85 GHz using the Effelsberg 100-m radio telescope. This survey aimed at weak pulsars (S< 0.5 mJy) which were not observed during the last survey (see Seiradakis et al. 1995).
We used a new sensitive HEMT system at 4.85 GHz recently
installed at the 100-m radio
telescope. The system with a maximum bandwidth of 500 MHz
has a system temperature of
K for elevations above 20
. We used either
4 channels of a 
MHz filter bank as
a de-disperser for two circular polarizations or broad-band signals
with 500 MHz bandwidth
or a narrow-band polarimeter
with a bandwidth of 80-200 MHz for full polarimetry observations
(see Hoensbroech et al. in preparation).
The filter bank was
used in order to reduce the dispersion broadening for pulsars where
the effect was significant (larger than P/1024, where P is the pulsar
period), in particular for objects with a high DM.
A detailed description
of the observing system and the calibration procedure can be found in
Seiradakis et al. (1995) and Kramer et al. (1996).
During about 80 hours of total observing time we observed 108 pulsars. The average integration time for detecting a pulsar was about 10-15 minutes.
