About the Data

  • Data Description
    Data DescriptionProposal: A description of the observations, their scientific justification, and the links to the data available in the science archive.

Compass and Scale Image of the GOODS/ERS2 Field
Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

The image is a composite of separate exposures made by the WFC3 and ACS instruments on the Hubble Space Telescope. In total, 10 filters were used to sample a very wide wavelength range. The color results from assigning different hues (colors) to combinations of the monochromatic images. In this case, the assigned colors are: Red: WFC3/IR F125W + F160W Green: ACS/WFC F606W + F775W + F850LP + WFC3/IR F098M Blue: WFC3/UVIS F225W + F275W + F336W + ACS/WFC F435W

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
