Suprime-Cam: Subaru Telescope Object Exposure Log, 2001-2005

An 80-megapixel mosaic CCD camera, Suprime-Cam provides a unique 34' x 27' field of view for the 8.2m Subaru Telescope. This table logs exposures with observation type 'OBJECT' made since April 2001, with a significant increase in rows from November 2005 after including data with position errors up to 30 arcseconds. NASA HEASARC created this service in September 2007 based on data from the Centre de Données astronomiques de Strasbourg.

Use Cases

• Studying the performance and characteristics of a large-format mosaic CCD camera based on the detailed technical specifications.
• Analyzing the temporal distribution of 'OBJECT' observations for survey planning based on the exposure log.
• Investigating the impact of positional accuracy on data inclusion by comparing pre- and post-November 2005 log entries.
• Calibrating or validating other astronomical datasets using the reported median seeing of 0.61 arcseconds in the I_c-band.

Strengths

• Logs exposures from a major 8.2m telescope instrument with an 80-megapixel (10240 x 8192) camera.
• Covers a wide temporal range, with observations starting in April 2001 and extending to at least November 2005.
• Includes detailed instrument specifications, such as a 0.202 arcsecond per pixel resolution and a median seeing of 0.61 arcseconds.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes the log excludes exposure types like 'BIAS' and 'FLAT', presenting a partial view of all observations.
