Obviously, spectral and spatial characteristics of the source now become intertwined and further treatment dependent on specific source models. Go back to Table of Contents . The six baselines between the four 8m Unit Telescopes are considered in this study only. There are too many Auxiliary telescope stations to consider them all, and the magnitude of the field effects are comparable to those of the UTs. Figure 1 shows the location of the Unit telescopes in a NE coordinate system.
Effective baselines depend on the position of the source.
The following table presents the specifications of the MIDI instrument which are considered relevant for the study. The relative effects in the Q band would be about 2 times smaller. The entire N band is considered for completeness only. This corresponds to 0.516 arcsec in the sky. Go back to Table of Contents .
