| L-Band: | 1.33GHz to 1.43GHz and 1.57GHz to 1.73GHz | ||
| C-Band: | 4.5GHz to 5.2GHz and 6.0GHz to 6.8GHz | ||
It is envisaged that frequency flexibility between L, C-Bands will be available. This flexibility will permit frequency band changes between complete observing runs. The Lovell Telescope will be available for short periods only during Semester 09A. Prospective users must make a strong case since the available time is likely to be heavily oversubscribed.
Please note that during Semester 09A MERLIN
operations will continue at a reduced level as e-MERLIN is commissioned.
Observations will be on a 'best efforts' basis and the MERLIN operations
team will make every effort to obtain data for highly-rated proposals.
Not all MERLIN antennas may be available during Semester 09A and observations
may have to be restricted to a sub-set of telescopes.
Please note that K-Band will not be available during Semester 09A.
Some e-MERLIN commissioning time is expected to
become available during Semester 09A. Further details will be released
on the e-MERLIN web pages during the Semester.
The system parameters for observation of a continuum source in good weather conditions are:-
L-Band C-Band
Maximum angular resolution ~ 150 ~ 40 (mas)
R.M.S. noise level for 12 hr. on source ~ 60/30 60/30(uJy/beam)
Maximum bandwidth per polarization ~ 15 ~ 15 (MHz)

*There will be MERLIN+EVN observations during Semester 09A. Applications to go to the EVN PC.
The maximum rate at which the observing frequency can be switched within an observing band will be approximately once every five minutes for multi-frequency synthesis (MFS) observations.
For spectral line work throughout the Semester, users are referred to Table 4.4 of the MERLIN User Guide Version 3 which is now available online. The maximum number of frequency channels per baseline to be divided between the 4 polarizations for bandwidths of 16 MHz, 8 MHz and 4 MHz are 64, 128 and 256 respectively. The number of frequency channels per baseline to be divided between the 4 polarizations will be 512 for bandwidths of 2 MHz or less . The minimum total bandwidth is 250 kHz.
