Background
The SRDP webpage states that "The SRDP pipeline is optimized for continuum science. Observations should have wide (~1 GHz or wider) bandwidths (i.e. be focused on continuum science, not on narrow spectral lines)."
However this can lead to some ambiguity when the observation is in a grey area between "obvious" spectral line (e.g. very narrow spectral windows) and "obvious" continuum (large bandwidth close to or equal to the maximum in that band).
Therefore the following criteria should be used for SRDP: (note: these are criteria for correlator tuning, not other criteria like which flux density calibrator was used)
- For C-band and higher, if the tuning includes 3-bit (i.e. it's purely 3-bit or it's mixed 3-bit/8-bit) this indicates continuum science (or that it can be used for reliable continuum science) and it qualifies as SRDP.
- For C-band and higher, If total bandwidth is less than or approximately 2GHz (technically, 2.048GHz), i.e. it is a pure 8-bit observation, check the proposal abstract to see if the primary aim includes continuum or spectral line (or both). If the abstract states that the science goals include continuum, then it is SRDP. If it includes continuum and specline, then it is still SRDP. If it includes specline but does not mention continuum, then it is non-SRDP. (Feel free to double-check with a Stage 2 Reviewer if unsure).
- Currently L-band and S-band are non-SRDP. If/when they are eventually added to SRDP, use the following criteria:
- for L-band: at least 1 GHz of total bandwidth, and no individual basebands < 500 MHz
- for S-band: at least 2 GHz of total bandwidth, and no individual basebands < 1000 MHz in L-band.
