Dec 1, 2025December 2025: CARTAvis/carta-frontend delivered two major frontend enhancements that drive business value by expanding data accessibility and improving image viewing consistency. The Catalog API now retrieves all VizieR columns, enabling richer data exploration for users. The Image Viewer UI polish fixed multi-panel alignment in partially filled layouts and added text wrapping in the cursor info bar to prevent overflow in narrow panels. These changes reduce the need for manual field requests, improve readability, and accelerate data inspection workflows across teams.
