Simulation for fringe fit test: MeqSilhoutte fixed delay
<p>A simulated observation of a point source with fixed delay offsets for each individual antenna. The dataset contains 5 minutes of simulated visibilities and is in MS format. </p> <p>The target is a point source at the position of 3C279. The antenna positions are for the VLBA, there are 10 antennae in total. Each has a non-zero, constant delay value implemented in the simulation. The observing frequency is 44GHz divided into 64 channels. </p> <p>This original simulation has an off-by-1 error in the channel handling, which implies that the delay solutions obtained from a fringe fit will result in a 1.5% (1/64) offset compared to the input delays. This makes this dataset an excellent test for future fringe fitters, as they should be able to recover this offset.</p> <p>The input delay values in seconds for each individual antenna are:<br> 1: 5.93E-11<br> 2: 5.03E-11<br> 3: 9.88E-11<br> 4: 1.61E-11<br> 5: 1.51E-11<br> 6: 3.80E-12<br> 7: 0.0<br> 8: 2.12E-11<br> 9: 1.14E-10<br> 10: 7.16E-11<br> </p>
