The TESS Project has allocated a number of two-minute cadence targets for programs that fall outside of the exoplanet, asteroseismology, and Guest Investigator programs. Proposals for these Director’s Discretionary Targets (DDT) can be submitted at any time, using the process described below.
For the TESS Extended Mission (Sectors 27-56), up to 1500 DDT targets per sector will be allocated for 2-minute data targets. In addition, 60 targets will be available for DDT observations at 20s cadence.
Approval process:
-
Targets reviewed by the TESS PI, a science expert selected by the TESS PI, and the TESS operations team.
-
Principal requester will be notified via e-mail and approved targets will be posted here, along with the expected time(s) of observation. There is no proprietary period for approved DDT observations.
-
Data from a DDT observation will be delivered to the TESS archives concurrently with the non-DDT data from the sector in which the DDT is observed
