About the Data
Note: Ground-based image data provided by R. Gendler and J. GaBany was used to fill in or supplement areas where HST data did not exist or was limited.
Data Description: The image was created from Hubble data from proposal 11570: A. Riess (STScI) and collaborators. Other ACS and WFPC2 datasets from various other proposals were used to augment this proposal's data.
Instrument: ACS, WFPC2, WFC3/UVIS
Filters: F435W (B), F555W (V), F606W (V), F656N (H-alpha), and F814W (I)
About the Image
Image Credit: NASA, ESA, the Hubble Heritage Team (STScI/AURA), and R. Gendler (for the Hubble Heritage Team)
Release Date: February 5, 2013
Color: This image is a composite of separate exposures acquired by various Hubble instruments and ground-based telescopes. Several filters were used to sample various wavelengths/frequencies. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
ACS: F814W (I) luminosity
ACS: F814W (I) red
WFC3: F814W (I) red
WFPC2: F656N (H-alpha) red
ACS: F555W (V)+F606W (V) green
WFC3: F555W (V) green
ACS: F435W (B) blue
Orientation: Compass and Scale Image of M106
