When Do Discrete Actions Make Good Continuous Controllers?
Zeji Yi, Soham Dasgupta, Xinyang Zhang +5
Though modern AI models like LLMs predict discrete tokens, today's robotic foundation models represent actions as continuous vectors. In this paper, we challenge this common consen…
Spatially Scanned STIS Spectra of the Exoplanet Host Star 55 Cnc
D. E. Welty, J. D. Lothringer, D. K. Sing +3
We discuss the analysis of two sets of optical/near-IR spectra of the exoplanet host star 55 Cnc, obtained with the Space Telescope Imaging Spectrograph (STIS) and grating G750L in…
Updated Sensitivities of the Five STIS L-mode Gratings
Amy M. Jones, Svea Hernandez, Joleen K. Carlberg +1
Re-derivation of the sensitivities of all of the Space Telescope Imaging Spectrograph (STIS) observing modes were required after major updates were introduced to the model atmosphe…
STIS Cycle 30 Calibration Programs
D. Welty, R. Bohlin, J. Carlberg +8
We discuss the suite of STIS calibration programs executed during HST Cycle 30, covering the period 2022 Nov 07 through 2023 Nov 05. For each of the 19 current regular calibration…
