    Description

      SKA1-SYS_REQ-3458 "SKA1 Mid Spectral Stability" reads:

      The bandpass of SKA1_Mid, on timescales of 600 seconds or less and for all processed bandwidths, post-calibration and RFI mitigation, shall be stable to better than 0.03%.

       

      According to https://jira.skatelescope.org/browse/SLSRO-196, the SPFRx ddDDR pointed out that the value of 600s is not long enough. A better value should be provided. To do this, simulations / analysis may be required.
