(NOAO Deep Wide-Field Survey Cetus Field, NDWFS Cetus Field)
(moderate size survey field)
The Cetus Field is a 9-square-degreesurvey field,
one of two fields defined in the late 1990s,
chosen as relatively free of infrared cirrus,
for the NOAO Deep Wide-Field Survey (NDWFS),
an optical/NIRsurvey.
The other NDWFS survey field is the Boötes Field.
The expression deep wide indicated the survey would
provide what was normally thought of as a
deep-field level of detail, but over a wider field,
reflecting the technology improvements of the time.
Both the NDWFS survey fields have been the target of
subsequent surveys, but the Cetus Field has been less-reused
than the Boötes Field.
A subset of each of the two fields were used by the Large Area Lyman Alpha Survey (LALA Survey),
and its Chandra X-ray Observatory followup.
