Guide to Image Cutout and Catalog SearchSince 1994 the FIRST survey has provided image cutout services that provide quick access to radio images of the sky. In 2005 we added images from our radio survey of the Galactic plane, MAGPIS. Over the decades since we incorporated imaging data from many other Galactic plane surveys to enable easy access to multi-wavelength imaging of the Milky Way. We also have data products for the high-resolution 1.4 GHz VLA survey of SDSS Stripe 82 from Hodge et al. 2011 and Hodge et al. 2013.
This page provides an overview of all our imaging surveys.

The MAGPIS survey is a 1.4 GHz Multi-configuration (B,C,D) VLA images; see the GPS home page for information on other surveys including Spitzer near IR, far IR, millimeter, and 6 cm to 90 cm radio observations. The color cutouts interface can combine multi-wavelength observations to make color images. |
| Stripe 82 survey | Search | Cutouts | SDSS Stripe 82 region: 92 deg2 of the equatorial stripe in the southern Galactic cap: 22h06m < RA < 23h21m, -1°21' < Dec < +1°21' 00h39m < RA < 02h21m, -1°21' < Dec < +1°21' | High-resolution 1.4 GHz A-configuration VLA survey covering the SDSS Stripe 82 (Hodge et al. 2011, Hodge et al. 2013) |
| SDSS3 JVLA survey | — | Cutouts Color cutouts |
Wide-band JVLA 1-2 GHz observations taken in the SDSS3 southern Galactic cap: 20.5h < RA < 4h, -9° < Dec < 15° |
Data acquired after the VLA upgrade to complete coverage of the SDSS southern region. This data was used in the FIRST survey (Helfand, White & Becker 2015), but the cutout service splits the observations into two bandpasses and also shows polarization images for the bandpasses. The sky coverage is spotty since only regions not previously covered by FIRST were observed. |
| NOAO DWFS survey | — | Cutouts Color cutouts |
VLA 4.86 GHz observations covering NOAO DWFS region: 2h03m15s < RA < 2h16m45s, -5°38' < Dec < -3°33' |
VLA 6 cm D-configuration observations of the southern (Cetus) region of the NOAO Deep Wide Field Survey. The cutouts page also shows FIRST survey cutouts for comparison. The color cutouts page combines these 6 cm and FIRST 20 cm data to make a color image. |
