ATCA Observations

Observations of PKS 1353-341 and PKS 1814-637 were ma-de on 1998 January 16, 17 and 19 using the 6A array at central frequencies of 1161 and 1336 MHz, respectively. The observation of 1934-638 was made on 1995 September 15 with the 6D array at a central frequency of 1201 MHz. The bandwidth of 8 MHz was subdivided into 512 channels, each of width 15.6 kHz, and later Hanning-smoothed to a resolution of 31.2 kHz, corresponding to a rest-frame velocity resolution between 7.0 and 8.1 km s^-1, depending on the observing frequency. PKS 1353-341 is weak (0.64 Jy at 1161 MHz) and was observed for a total of 5 h. PKS 1814-637 (13.2 Jy at 1336 MHz) was observed for a total of 1 h. PKS 1934-638 was observed for a total of 6 h. The average system temperature for PKS 1814-637 was 37 K, but for PKS 1353-341, which was observed below the nominal frequency limits of the ATCA, the average system temperature was 85 K and for PKS 1934-638, 55 K. Except for PKS 1353-341, the bandpass calibrators listed in table were observed for approximately the same length of time as the corresponding sources.
