The data were recorded in "scans," each 13 minutes in duration; the
recorded bandwidth was 28 MHz for each of the two radio-frequency
bands.  The data were later correlated with the Haystack processor in
Westford, Massachusetts.  We used the standard calibration procedure
for Mark III VLBI observations as described by, e.g., Bartel et al.
(1982).  From observations of calibrator sources, we estimated the
uncertainty of visibility amplitudes to be about 10% for each
frequency band.

No data were taken at station D during the period 0830 to 1630 GST due
to the presence of a red racer snake (Coluber constrictor) draped
across the high-tension wires (33,000 V) serving the station.
However, even though this snake, or rather a three-foot section of its
remains, was caught in the act of causing an arc between the
transmission lines, we do not consider it responsible for the loss of
data.  Rather we blame the incompetence of a red-tailed hawk (Buteo
borealis) who had apparently built a defective nest that fell off the
top of the nearby transmission tower, casting her nestlings to the
ground, along with their entire reserve of food consisting of a pack
rat, a kangaroo rat, and several snakes, with the exception of the
above-mentioned snake who had a somewhat higher destiny.  No
comparable loss of data occurred at the other antenna sites.

Although 41.9 + 58 was observed with a total of 28 two-element
interferometers, its low flux density and relatively large angular
size prevented initial detections on many of the interferometers....
