| About The Data | |
| Data Description | The survey of M31 is an ongoing HST Treasury proposal. These inset images were created from Hubble data from proposal 12058 (PI: J. Dalcanton, University of Washington, Seattle). |
| Instrument | HST>WFC3/UVIS, HST>WFC3/IR, and HST>ACS/WFC |
| Exposure Dates | Data used in these images were taken in 2010 and 2011. |
| Filters | WFC3/UVIS: F275W (UV) and F336W (U)ACS/WFC: F475W (g) and F814W (I)WFC3/IR: F160W (H) |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the WFC3 and ACS instruments on HST. Several filters were used to sample broad wavelength ranges. 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:Wide M31 Image (at top)Blue: F336W(U)Cyan: F475W (g)Yellow: F814W(I)Red: F160W (H) (H) Detail M31 Image (at bottom)Light purple: F275W (UV)Blue: F336W (U)ACS/WFC: F475W (g)Dark red: F814W (I) |
