What's New

What's New in the NOAO Science Archive

V2.6: 03 Jan 2011

Outer Limits Survey:Stellar Pop at the Extremities of the Magellanic:
- Description of survey can be found here.

The NEWFIRM Medium-Band Survey (NMBS): accurate redshifts for 40,000 K-selected galaxies:
- The data release includes deep NIR medium-bandwidth photometry in the J1, J2, J3, H1 and H2 bands over the wavelength range 1-1.8 microns, as well as broad-band K, in the AEGIS and COSMOS fields. The observations were carried out on the Mayall 4-m telescope on Kitt Peak using the NOAO Extremely Wide-Field Infrared Imager (NEWFIRM). We describe the full details of the observations, data reduction and photometry in a forthcoming paper (K. Whitaker et al. submitted to ApJ). Additional information is also available through the project's web site (www.astro.yale.edu/nmbs).

A NEWFIRM Survey of the SDWFS/NDWFS Field
- The Infrared Bootes Imaging Survey is a near-infrared imaging survey covering the entire Spitzer Deep Wide-Field Survey (SDWFS) region, which corresponds to the Bootes field of the NOAO Deep Wide-Field Survey. This public release includes data from 52 subfields that together span the region, and that overlap with one another by roughly 2 arcmin on each side. We provide both the final reduced images and J-band selected, line matched catalogs for all subfields. Along with these images, we also provide weight maps from the SWARP software, and flag images denoting regions with poor data (more details can be found here).

V2.5: 22 May 2009

ChaMPlane: Measuring the Faint X-ray Binary and Stellar X-ray Content of the Galaxy:
- We have received 1427 fits images from the The Chandra Multiwavelength Plane (ChaMPlane) Survey project. It includes 65 fields from KPNO observations from 2000-2004 and CTIO observations from 2001-2005, approximately 350GB total. Additional information is provided through the project's web site.

V2.4: 18 Mar 2007

zBootes : z-band Observations of the NOAO Deep Wide-Field Survey Bootes Field:
- Optical imaging obtained for zBootes, a z-band survey of the NOAO Deep Wide-Field Survey Bootes Field using the Steward Observatory 2.3m Bok telescope and the 90Prime imager. The zBootes imaging covers 7.62 of the NDWFS survey area and reaches a mean 50% completeness limit of 22.8 mag in the z-band. For details see zBootes.

Faint Sky Variability Survey (FSVS):
- The Faint Sky Variablity Survey (FSVS) provides a database for studying faint populations and their variability, spanning 16-24 mag across the optical regime using the B, V, and I filters with time-sampling obtained in the V band over tens of minutes to years. With a total area coverage of 23 sq. degrees at moderate-to-high Galactic latitudes, the FSVS also provides a sample spanning relatively different Galactic populations. The FSVS was part of the Isaac Newton Telescope (INT) Wide Field Survey. The INT is operated on the island of La Palma by the Isaac Newton Group the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofisica de Canarias. In addition to the images available in the Archive, the FSVS Photometric and astrometric catalogs can be found on the Archive FTP site at FSVS Catalogs.

V2.3: 1 Oct 2006

FLAMEX Public Data Release DR1 (Bootes):
- The FLAMINGOS Extragalactic Survey (FLAMEX) is a deep, near-infrared imaging survey covering 7.1 square degrees within the NOAO Deep Wide-Feld Survey (NDWFS) regions. FLAMEX is the first such deep, wide-area survey to image in both the J and Ks filters, and is larger than any previous NIR surveys to comparable depth. This is a release of the FLAMEX survey images of the BOOTES field, the complete catalog for the BOOTES field can be obtained from the FLAMEX web site Public Data Release.

V2.3: 12 June 2006

SINGG Release 1.0 now available:
- Survey for Ionization in Neutral Gas Galaxies (SINGG), a census of star formation in Hi-selected galaxies. The new datasets focuses on 93 SINGG targets whose observations have been fully reduced and analyzed to date. The majority of these show a single Emission Line Galaxy (ELG). There are multiple ELGs in 13 fields, with up to four ELGs in a single field. Details of the SINGG survey can be found at the SINGG web site.

V2.2: 13 Dec 2005

XBootes X-ray-optical merged catalog now available:
- The XBootes Survey is a 5-ks Chandra survey covering the Bootes Field of the NOAO Deep Wide-Field Survey (NDWFS). This catalog presents the 3,213 X-ray point-source in the XBootes survey which overlap with the NDWFS data. This catalog can be obtained from our anonymous FTP site (xbootes). See the about_xbootes.txt for more detail.

V2.2: 22 Oct 2004

Updated/new data release:
- NDWFS Data Release 3: Includes all the Mosaic-1 optical and ONIS K-band imaging of the Boötes Field of the NDWFS (9.3 square degrees in area); 101 images with accompanying SIGMA (SIG), RMS files and MASK fiels. Object Catalogues available from the survey site.

V2.1.1: 2 June 2004

NOAO Science Archive - La Serena site is now available.
The addition of the La Serena web site, is part of a broader NOAO goal to bring convenient access to archived astronomy data in both hemispheres.

V2.1: 2 March 2004

New data release:
- 32 MOSAIC images from the First Look Survey.

V1.1: 27 June 2002

Data Release 1, Version 2 of the NOAO Deep Wide Field Survey is available. This release/version uses images stacked with exposure time weighting of the individual input images to produce an approximate 1/variance weighting, resulting in an improved signal-to-noise ratio. Version 2 also includes net exposure masks (_exp.fits suffix), rejected pixel masks (_nrej.fits), and bad pixel masks (_bpm.fits). While the preview GIFs and thumbnails of the actual images are provided in a negative greyscale format, the mask previews are color-coded to make them easy to distinguish from the science images and from each other. The bad pixel masks use a positive red look up table (LUT), and the rejected pixel masks and exposure masks use green and blue LUTs, respectively. Additional discussion regarding the new version of these data are available.

Data Release 1, Version 1 are no longer accessible via the NSA Web interface. However, these data can be acquired via ftp download.

Users can now sort the results of an archive search using the RA and Dec labels on the output columns. For example, clicking on RA will sort the records in ascending order according to the RA values; clicking again will reverse the order of the sort.
Updated The Resolved Stellar Content of Local Group Galaxies survey description and investigator list.
New features and other changes to the NSA are now catalogued on this What's New page.
