The 100-m radio telescope at Effelsberg has been used in the total power mode (ON-OFF) combining a reference field 5 min earlier in RA with the on-source position. The dual channel HEMT receiver had a system noise of 30 K. The 1024 channel autocorrelator was split into 4 bands (bandwidth 6.25 MHz) of 256 channels each shifted in frequency by 5 MHz with respect to their neighbor in order to cover a velocity range from -470 to 3970 kms-1 overlapping 1.5 MHz between channels. The resulting channel separation was 5.1 kms-1 yielding a resolution of 6.2 kms-1 (10.2 kms-1 after Hanning smoothing). The H I profiles observed with the 100-m radiotelescope are presented in Fig. 1 in order of increasing RA as in Table 1. The half power beam width (HPBW) of the Effelsberg telescope at this wavelength is 9 3.
