It should, of course, not be forgotten that if any programmes, particularly those investigating and monitoring variable sources, do not require the Mk2 telescope in the array, it will be possible to switch between the two frequencies throughout the observing programmes, thus effectively observing almost simultaneously in the two frequency bands.
The maximum angular resolutions at C-Band and K-Band are ~40 and ~8 milliarcseconds and the minimum rms noise levels in maps of continuum sources will be ~50mJy per beam and ~400mJy per beam for 12 hour on source observations respectively. The maximum bandwidth per polarisation for both frequencies remains at ~15MHz.
For spectral line work throughout the semester, users are referred to Section 3.4 of the MERLIN User Guide Version 1.1. However, the number of frequency channels per baseline to be divided between the four polarisations will be 512 for bandwidths of 2 MHz or less. The minimum total bandwidth is 125 kHz. The maximum number of frequency channels per baseline to be divided between the four polarisations for bandwidths of 16 MHz, 8 MHz and 4 MHz are 64, 128 and 256 respectively.
