The Dwingeloo Radio Telescope

The monitor can also be switched in the hardware to measure the sampling levels of the A/D converters for test purposes

(2)

The correlator hardware starts with 20-bits and integrates in a buffer up to 24bits; these are then read out by the 32-bit multiplexer, so the least significant 8 bits are zeros.

The nominal value is "15K"

(4)

actually it is closer to 160.0047MHz

(5)

actally it is nearer to 160.0047MHz

(6)

The accuracy needed scales with the beam width, so that a 1 second accuracy is needed at 6cm

(7)

Divide by the wavelength of the line (in mm) to go from km/s to MHz, a positive velocity is lower frequency. The difference between LSR and barycentric is about 20km/s.

These observations were made in 1988 and 1989.
