---

12.5.1 Raw NUV ACQ/IMAGE Data

The raw data for ACQ/IMAGE is 1024 × 1024.

12.5.2 Corrected NUV ACQ/IMAGE Image

The corrected image is 1024 × 1024 × 16 bits and includes effective counts sec^-1, the gross counts multiplied by a pixel's EPSILON factor and divided by the exposure duration. Note that acquisition images are not calibrated by the pipeline, but exposures obtained in imaging mode are.
