Notes. For the Arecibo surveys we chose to adopt a more accurate definition for the gain and the receiver temperature that are function of the declination δ. Respectively from the left to the right column, are indicated: telescope gain divided by a system losses factor, minimum signal to noise detected, receiver temperature, central observation frequency, integration time, sampling time, total bandwidth, and channel bandwidth.
