About The Data
Data Description Abell S1063 is part of the Frontier Fields Program. These data are from the HST proposals (PI: M. Postman, STScI), 13459 (PI: T. Treu, UCLA), (PI: J. Lotz, STScI), and 14209 (PI: B. Siana, UC Riverside).
Instrument HST>ACS/WFC, HST>WFC3/IR
Exposure Dates December 2005 – May 2016
Filters HST>ACS/WFC: F435W (B), F606W (R), and F814W (I) HST>WFC3/IR: F105W (Y), F125W (J), F140W (JH), and F160W (H)
About The Image
Color Info These images are composites of separate exposures acquired by the WFC3/IR and ACS/WFC instruments. Several filters were used to sample various wavelengths. 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: Blue: ACS/WFC F435W (B) + F606W (R) Green: ACS/WFC F814W (I) + WFC3/IR F105W (Y) Red: WFC3/IR F125W (J) + F140W (JH) + F160W (H)

About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
