During our analysis we see some evidence of the beam squint effect that is introducing instrumental CP to the observations. To address this effect and hopefully mitigate it we would like to perform and elevation-dependent analysis (which is the main parameter affecting beam squint) and for that we need to recover the elevation of each antenna at any given scan i<span style="">n the experiment.</span></div><div><span style=""><br></span></div><div><font>Is there a possibility to extract this information through AIPS in a metadata or table format?
