Tied Array Mode: Tied Array Mode observations produce a possibly large number of tied array beams from all receptors in the instrument, or a subset thereof. The resulting voltage sum output of each tied array beam may be presented either as a series of spectral channels or transformed back into a time series. More dedicated data products are possible as well: e.g. for flux density monitoring of single pixels on the sky. In this operation mode a large quantity of raw data is collected; however time averaging can be applied to each of many beams to achieve the necessary compression. Transient Detection Mode: for Transient Detection Modes, the final data-products are typically event-lists, possibly combined with raw time-series replayed from station level data-buffers. Buffered data may be (re-)processed centrally, resulting in more specific data-products.
