Which frequency setup is possible for solar observations?

Authors list

 Only proposals for continuum observations in Bands 3, 5, 6 and 7 will be accepted. For the interferometric observations, these will be obtained using the low spectral resolution (TDM) mode, and the high spectral resolution (FDM) mode is not offered (please see Appendix Section "Solar Observations" in Cycle-10 Proposer's Guide).
