tlpipe.timestream.time_flag.RawTimestream.apply_mask

RawTimestream.apply_mask(fill_val=(nan+nanj))

Applying vis_mask to vis with the fill_val.

NOTE: This is a non-invertible operation to the dataset vis, as its values corresponding to True of vis_mask will be replaced by fill_val and lost. Usually you may prefer to use masked_vis() instead.
