simulator.corrupt - Function

2.4.1 Corrupt the data with visibility errors

Description

Add errors specified by the set* functions (such as noise, gains, polarization leakage, bandpass, etc) to the visibility data. The errors are applied to the DATA and CORRECTED_DATA columns.

Note that corrupt handles only visibility-plane effects, not image-plane effects such as pointing errors and voltage patterns, which get applied in predict. Note, the function applies errors to both cross- and auto-correlation data; The auto-correlation data are corrupted properly only for the thermalnoise set by setnoise.

Arguments

Returns
bool

Example

    sm,openfromms(’3C273XC1.MS’);
    sm.predict(’3C273XC1.FAKE.IMAGE’);
    sm.setnoise( mode=’simplenoise’, simplenoise=’0.1Jy’);
    sm.setpa( mode=’calculate’);
    sm.corrupt();
