Implementations

impl PreprocessContext

pub fn preprocess(
    &self,
    corr_ctx: &CorrelatorContext,
    jones_array: &mut Array3<Jones<f32>>,
    weight_array: &mut Array3<f32>,
    flag_array: &mut Array3<bool>,
    durations: &mut HashMap<String, Duration>,
    vis_sel: &VisSelection
) -> Result<(), BirliError>

Preprocess visibilities for a chunk of correlator data

Arguments

• corr_ctx - marlu::mwalib::CorrelatorContext
• jones_array - Array of Jones visibilties
• weight_array - Array of weights associated with Jones visibilities
• flag_array - Array of flags associated with Jones visibilities
• durations - Hashmap used to record timing info

Errors

will wrap errors from correct_digital_gains, correct_coarse_passband_gains

TODO: more granular error types: PreprocessingError -> {DigitalGainsError, etc.}
