What is a DRZ file?
Graphic file created by Draz Paint, an older image editor for the Commodore 64 system; rarely ever used as a bitmap image format now, but can still be opened by XnView.
File Type 2PyDrizzle Data File
.DRZ File Association 2
Data file created by PyDrizzle or MultiDrizzle--programs used for processing ACS and WFPC2 Hubble Space Telescope (HST) space photograph data; stores a "drizzled" image, which uses reconstruction techniques to fill undersampled areas of the image; used for creating quick-look mosaic images of space data; used in scientific space research.
DRZ files are based on the .FITS format and often are seen with the compound extension, ".drz.fits." However, the format is most often processed with custom imaging programs.
NOTE: ACS stands for Advanced Camera for Surveys. WFPC2 stands for Wide-Field Planetary Camera 2. Both ACS and WFPC2 are large cameras installed on the Hubble Space Telescope in different space servicing missions.
