The un-prepped data is not provided through the VSO to reduce unnecessary computational time overall; therefore, the calibration files are not distributed en masse. If you would like to request access to these files, please contact sabrina DOT savage AT nasa DOT gov.

Version 3 Updates


Several updates were made to the latest version of the Hi-C data which include:

- Corrections to the time stamps.

- Compensation for missing rows.

- Re-alignment after Hi-C time correction and missing row adjustment.

- Application of fine-alignment shifts.

- Additional dust and particle hits were removed.

- Intensity levels were normalized and more adequately scaled between the 1K set and 4K extractions and between quadrants.

- Application of absorption compensation.

- The method for stacking the 1K set was changed to more adequately scale after alignment. Separate stacked sets are provided to allow for analysis of high cadence sets.

- Two movie-quality sets were created that suppress noise.

- Alignment includes tracking to remove drift.
