in the Planetary Data System (PDS) by the Lunar Atmosphere and Dust Environment Explorer (LADEE) Ultraviolet and Visible Spectrometer (UVS) team. The document serves both as UVS's Data Product SIS and its Archive Volume SIS. It is written for scientists, software engineers, and others who wish to understand the contents of the UVS Archive, including users associated with the project and those in the general planetary science community. It explains the structure and contents of the archive, including a detailed description of the spectral data products and how they were generated. It describes the UVS instrument, its observational activities, and the data products produced by the UVS team and the steps used to derive them. It is intended to provide the information necessary to use and reproduce the data products. 1.1 Applicable documents and constraints The LADEE UVS SIS complies with the following documents: PDS4 Concepts, Version 1.0.0, May 1, 2013 Planetary Data System Standards Reference, Version 1.0.0, May 1, 2013 LADEE Data Management and Archive Plan, Revision A, September 5, 2013, document number C10.LADEE.SDMAP LADEE UVS Science Team and PDS Atmospheres Node Interface Control Document, Version 1.0, August 20, 2013 The descriptions of the instrument, settings, observational activities, raw data products, calibration, and relationship with the LADEE spacecraft are derived from the: LADEE PDS Mission Description, Revision 1.4, May 6, 2014, document number 12.LADEE.PMD LADEE PDS Spacecraft Description, Revision 1.2, March 14, 2013, document number 11.LADEE.PDSSD Colaprete, A., Vargo, K., Shirley, M., Landis, D., Wooden, D., Karcz, J., Hermalyn, B., & Cook, A. 2014, An overview of the LADEE Ultraviolet-Visible Spectrometer, Space Science Reviews, 185, 63–91, hereafter referred to as UVS Instrument Document 1.2 Relationship with other interfaces The UVS data products are stored in multiple locations according to the LADEE Project Data Management and Archive Plan (DMAP).
