EVLA Memo 145 On Determining Visibilities from Correlation Products
نویسنده
چکیده
The EVLA correlator will produce direct, unnormalized cross-power correlations, rather than the normalized correlation coefficients produced by the VLA correlator. This important change necessitates some changes in post-correlation correction of the correlator output in order to produce quantities which can easily be converted to the desired visibilities. This memo gives a simple analysis of the both systems.

متن کاملEVLA Memo #100 Correction of errors due to antenna power patterns during imaging
Errors in the observed visibilities can be classified as direction dependent and direction independent effects. Since direction dependent effects are different for each source, they must be corrected during imaging. This memo is concerned with the problem of correcting for such effects during imaging. We demonstrate that the effects of known receptor pointing errors (including polarization squi...
متن کاملEVLA Memo #127 On the Use of Correlation Coefficients for Determining Antenna Sensitivity
A simple method is developed to estimate antenna sensitivities through analysis of the array corrrelation coefficients. The accuracy of this method is demonstrated by comparison of the observed cold-sky noise with predictions based on this analysis applied to observations of 3C147. For nearly all cases, the predictions are within 2% of the observed values.
متن کاملEVLA Memo 131 Measurements of C-Band EVLA Antenna Polarization
A simple method for determining absolute antenna cross-polarization is described. Observations using this method were taken at C-band and the results are shown. The wide-band EVLA circular polarizers have high cross-polarization, exceeding 5% at most frequencies on most antennas. However, orthogonality between the RCP and LCP outputs is maintained, resulting in baseline-based cross-polarization...
متن کاملEVLA Memo 160 More WIDAR spectral dynamic range tests
This is a continuation of investigation of the spectral dynamic range achievable with the WIDAR correlator. Previous investigations (EVLA Memo 148) were limited by the so-called “splatter” phenomena, which is now understood and avoidable (EVLA Memo 157). This investigation is also stimulated by a desire to evaluate the “correlator chip beat artifact” seen in simulations (NRC-EVLA Memo 32) and t...
