September 2019 New Horizons Review ================================== MVIC KEM Cruise 1 and KEM1 Encounter Liens ========================================== Reviewers: Xiao-Duan Zou, Tony Farnham ====================================== CATALOG file: catalog/dataset.cat --> Unit description in file is unclear. What is the physical meaning of the value in images regarding MU69 observation: both level 2 and 3 --> Typo - Repeated "either." "This indicates either that the target was either a star, or that the..." --> DATASET.CAT file states that the dataset used to compute geometry is NH-X-SPICE-6-PLUTO-V1.0, but the dataset available from NAIF is NH-J/P/SS-SPICE-6-V1.0. Coverage ends before this dataset starts. Couldn’t find a more updated set of kernels. Can’t check the geometry in the headers and labels without updated kernels. Does the SPICE dataset ID in the DATASET.CAT file need to be updated? --> Under Version, there is text that begins, "Future datasets may include more data...". I'm concerned that the data are being released when they may be potentially incomplete. Thus, are there truly future data to be added to this dataset? file: nh-x-mvic-3-kemcruise1-v2.0/catalog/dataset.cat: --> Typo - Repeated "too" in sentence beginning, "The data taken on 12/30/2018 was targeted at MU69..." DOCUMENT file: document/seq_mvic_*1.tab: --> CODMAC levels are not consistent with /DATA. --> 19 files / 26 in seq KEMCRUISE1. 11 files / 60 in seq KEM1. More sequences are present in this file than in the data, suggesting the dataset is not complete. DATA file: data/*.fits headers --> Long list of SPICE kernel names. 101 kernels listed in both kem1 and kemcruise1 fits headers. kernel range: 2006~2025 but observation range only: 2017-01-28 ~ 2017-12-06 KEMCRUISE1, 2018-08-15 ~ 2018-12-31 KEM1 --> The units are not mentioned in level 2 header or label, DN? not integer. The units in level 3 header are NOT clear, (calibrated DN). --> SAPDESC = 'First Opnav Observation for Ultima Thule' / Science Activity Plan des…. Ultima Thule is a nickname, not the official designation for MU69. Technical Review: Tilden Barnes =============================== DATA_SET_ID: Should the KEM1 id not be '-X-' (for "Other") but '-A-' for "asteroid"? Or are we stating the KBOs are other? file: 'catalog/dataset.cat' --> ABSTRACT_DESC: The abstracts between KEMCRUISE1 and KEM1 are almost identical, yet don't they include different things? Most of the text makes sense for being the same, but I question if what is included is always the same. Perhaps I'm wrong. --> DATA_SET_DESC: The difference between KEMCRUIE1 and KEM1 are negligible. Should that be the case of for a cruise data set and then an encounter? The purposes and what is observed or done I would think would be different. Certification: Certified with liens. Will require check from reviewers if there is missing data.
