Users who wish to simulate the uv coverage of the MeerKAT interferometer for given source coordinates and observation duration can use the MeerKAT uv coverage simulator.

...

After declaring your variables in the User input cell, click Cells → Run All in the menu to execute the calculations and plot the uv coverage for your source using the menu at the top of the notebook. The output plots are frequency-independent and can be scaled by dividing by your wavelength of interest. We reproduce some example plots from MeerKAT specifications, which were produced using this simulator:

...

Detailed observation simulations can be done following the instructions given here.

Caveats

  • A continuous track is simulated

  • Currently it is not possible to stipulate a time-range for the simulation

  • The track is symmetrical about zenith transit

Examples

...

Targets towards northern declinations are above the telescope’s minimum elevation of 15° for shorter durations. The calculator will tell you how long the target will be above the set horizon limit. This can be set to higher elevation ranges but please note that observations will be scheduled at elevation/LST ranges that maximise telescope scheduling efficiency.
