ESO TELBIB SELECTION CRITERIA:

Papers that ‣ partly or exclusively use ESO data

(proprietary or archival) —> included

Papers that ‣ quote results from literature ‣ mention ongoing projects ‣ suggest future observations ‣ describe instrumentation / software ‣ use data in models or simulations merely as examples ‣ use images only as visual reference

—> excluded

Instrumentation management


Do any observing facilities need upgrades? Should they even be replaced?



‣ Planning tools:

✴ knowledge of community’s needs, demand for observing time [not in telbib] ✴ number of papers ✴ number of citations ✴ citation flux curves: citations by year of citing paper

Based on Kulkarni, arXiv:1606.06674: “Instruments with decreasing overall citation counts should be upgraded or replaced.”



‣ Example 1: HAWK-I

Questions we cannot answer


3

Questions we cannot answer

‣ Subject analyses + trends in topics (will the UAT help?)

‣ Author gender studies (ORCID?)

‣ No “weights” assigned to data in papers (1 spectrum vs. multiple observations vs. big data sets)

‣ telbib results can become “blurry” for papers with many programs with different characteristics


Take-away Points


1. telbib is curated ‣ curation = “to take care of” ‣ workflow ensures quality content ‣ including, but not limited to linking programs to papers

2. telbib provides insights ‣ numerous statistics, reports, and visualizations ‣ large range of parameters ‣ data available for 20+ years ‣ tool to understand publishing trends

3. telbib has many facets — and some limits ‣ not all questions can be answered ‣ continuous enhancement with new features
