Attaining Spectral Energy Distributions With Sub-Percent Uncertainties: All-Sky DA White Dwarf Spectrophotometric Standard Stars For Large Telescopes And Surveys
Abhijit Saha, Edward W. Olszewski, Benjamin M. Boyd +14
We present a synopsis of the project to establish thirty-two new faint () DA white dwarfs as spectrophotometric standards distributed over the whole sky. O…
New Time-Dependent WFC3/IR Inverse Sensitivities
Annalisa Calamida, Mariarosa Marinelli, Varun Bajaj +2
We present new time-dependent inverse sensitivities for the WFC3/IR channel. These were calculated using the sensitivity change slopes measured by \citet{2024wfc..rept....6M} and p…
WFC3/UVIS Geometric Distortion -- Time Evolution of Linear Terms w.r.t Gaia
Anne O'Connor, Varun Bajaj, Jennifer Mack +1
We align more than 7,400 WFC3/UVIS exposures to the Gaia DR3 catalog to examine the time evolution of the linear terms (shift, rotation, scale and skew) of the geometric distortion…
On the radial distribution of horizontal branch stars in ngc2808
G. Iannicola, M. Monelli, G. Bono +17
We present accurate new ultraviolet and optical BVI photometry for the Galactic globular cluster ngc2808, based on both ground-based and archival HST imagery. From this we have sel…
