imager.uvrange - Function

2.3.1 Select data within the limit of a given range


Description

Apply a uvrange so that only points within a given uvrange are selected for further usage. To be noted selectvis if used after uvrange will reset the selected range. So selectvis should be used prior to uvrange or can be used

to reset it if one changes one’s mind. The points are not flagged! Further point to be noted for spectral line data the uv distance is calculated using the mean of the wavelengths of the different spectral channels selected.
