Readme.txt gives a high-level overview of the PIXL Bundle.

The PIXL Bundle Software Interface Specification (SIS)  describes the contents, format, and structure of the bundle. Users who are unfamiliar with PDS archives should read this first.

The PIXL PDS User Guide summarizes information from other documents that is likely to be most useful to the science user.

The PIXL EDR SIS and PIXL RDR SIS describe the data products generated by the PIXL instrument suite, including how they are processed and labeled. The SISs are detailed documents intended for use in mission operations as well as by science users of the archive.
