KCWI Data Format

KCWI raw data files are in simple FITS format consisting of a single primary header/data unit (HDU) with 32-bit floating-point pixels.

An overview of the instrument is provided here while the different observing modes are described here.

KCWI uses a single e2v CCD231-84 4k x 4k CCD with 15 µm pixels, providing a pixel scale of 0.147 "/pixel. The full detector characteristics can be found here.

A data reduction pipeline is available for reducing KCWI data: information can be found here. Details on how to obtain and install the packages are provided on the referred pages.
