Rubin Nights Cache

Overview

The local cache contains 95,106 Rubin science visits across 223 cached LSSTCam nights. The covered science-visit range is 2025-06-20 to 2026-10-30. Source reports and derived data remain in the app-managed local cache.

The raw detail table also includes non-science rows. Across all cached image types there are 128,459 extracted rows, including acquisition, wavefront-sensing, focus and engineering-test entries where Rubin reported them.

Your object list is included. The current object file is objects.csv. Its observations are combined into 2,871 same-date groups using 60 minutes and a maximum 1 deg group diameter. With a +/-5 day window and a 1.75 deg Rubin field radius, 419 groups have a field candidate and 2,452 groups have no hit; both are retained.

Bands and limiting depth

The depth view is point-only. Color-channel buttons are additive, and the Min, Max, Mean and Median buttons can be combined without connecting the nightly points.

Observation types

No points are connected. Marker shape encodes the selected statistic; color encodes the band. The y-axis rescales to the active buttons.

Field coverage

The coverage plot uses a continuous date color scale. The From and To fields accept typed dates or calendar selection, remember the chosen range and reset to the complete Rubin interval. Playback is cumulative, RA runs right to left from 0..24 hours, and Dec is fixed to -90..+90 deg.

Play all is cumulative. Other modes show a window centered on the midpoint of the displayed night's observations. One month means 30 days.

Observation types

Rubin reported several image types and scheduler reasons. This site keeps science visits separate while also exposing acquisition, wavefront-sensing, focus and engineering-test rows from the cached detail tables.

Observation type counts — Derived observation-purpose groups based on img_type and scheduler reason.
