BiggSky XISF support - third-party notices

The notices and licenses for the third-party code in BiggSky's XISF reader and writer, reproduced here in full so you can read them before you download.

This page mirrors the THIRD_PARTY_NOTICES.txt file installed with BiggSky.

zlib and LZ4 are licensed to you under their own permissive terms, not under the BiggSky EULA. Any terms of that agreement which differ from theirs are offered by KB Imaging Solutions LLC alone.

BiggSky reads and writes XISF, the Extensible Image Serialization Format, version 1.0, as specified by Pleiades Astrophoto S.L. (https://pixinsight.com/doc/docs/XISF-1.0-spec/XISF-1.0-spec.html). The XISF implementation in BiggSky (the XISF MEX file) is independent software written for BiggSky from the published specification. It is not derived from, affiliated with, or endorsed by Pleiades Astrophoto S.L. PixInsight is a trademark of Pleiades Astrophoto S.L.

The XISF MEX file includes the following third-party software.
