Early phase of Gaia DPAC

 

GAIA-LL-060

Summary

The cross-matching problem for Gaia is reviewed in the context of standard statistical procedures for classification and cluster analysis. Classification is the appropriate method when an input catalogue of sources is available. Observations not cross-matched against a catalogue should instead be subject to cluster analysis to identify new sources. A procedure for cluster analysis that takes proper motion into account is developed and demonstrated. A coherent procedure for cross-matching according to these principles is outlined.

GAIA-C3-TN-UB-JP-011

Summary

In this note we define the concept of “TransitId”, the unique identifier of a Gaia observation used in the MainDB by several DPAC processes. We describe here its definition, which is based on the OBMT time scale. The present revision 5 describes the “human-readable” format of TransitIds.

GAIA-C3-TN-LU-LL-088

Summary

This technical note expands the minimum-dimension LSF modelling (GAIA-C3-TN-LU-LL-084-01) with a few more useful ideas: (1) that the LSF model is formulated such that the area normalization is implicit; (2) that the non-negativity of the LSF can be guaranteed by simple constraints on the parameters; and (3) that the model should work also with very few parameters, even without any parameters at all.

GAIA-C3-TN-LU-LL-136

Summary

This TN describes the expected astrometric properties of binaries in EDR3 and DR3 based on simple models of the distribution of binary parameters and how binaries are treated in IPD and AGIS. The results may be useful for understanding how different kinds of binaries show up in statistics such as the RUWE, and how they may behave in acceleration solutions. Possible criteria for selecting good 7p and 9p solutions are given.

GAIA-C4-TN-OCA-FM-061

Summary

This document presents the principles of the determination of the size of the solar system in kilometres based on Gaia observations of (433) Eros in February 2019 and (52768) 1998 OR2 during its Earth’s flyby of April 2020. The historical context is given to introduce the issue in a wider perspective and explain the value of such an exploitation of Gaia data for training and science education. Data analyses with different levels of modelling are discussed together with their results. Although there is no truly novel science to expect from Gaia in this area, it happens that thanks to the 1.5 million km baseline, the processing is relatively straightforward and despite the lack of refinement it ends up with the most accurate determination of the Earth-Sun distance with this important, although now outdated, technique.

GAIA-C5-TN-OABO-SMR-003

Summary

When trying to build a large set of ground based SpectroPhotometric Standard Stars (SPSS) for calibrating Gaia BP/RP Spectra and G-Band Images to a few % in absolute flux, it is essential to maintain the maximum homogeneity in data quality, acquisition and treatment. This Data Reduction Protocol concerns the QC on the SPSS pre-reduced photometric frames and the production of aperture photometry catalogues ready to be used for the analysis. The procedures followed to both quality check the pre-reduced 2D photometric frames and to obtain aperture photometry catalogues are described step by step.

Summary

We show how to combine posterior probabilities from an emsemble of models, each of which estimates the same parameter (or class) but using "independent" data. From this we describe how to separate out and replace the class prior (or the model-based prior) of a classifier post hoc and how this relates to the combination problem ...

GAIA-C8-TN-MPIA-CBJ-081

Summary

In this technical note, the estimation of distance and transverse velocity (as speed and direction) from Gaia parallax and proper motions, using posterior sampling, is investigated. The method is illustrated using TGAS data. The goal is not to suggest producing such estimates for the data releases, but rather to help educate users in their interpretation of the data.

GAIA-c8-TN-MPIA-CBJ-094

Summary

DSC or Direct Source Classifier classifies objects into five classes using BP/RP spectra and various features constructed from astrometry and photometry. The main focus is on the classes “quasar” and “galaxy”, as they are defined by our particular training data. ApsisOps3.2 (run 2) produces classification results for 1.8 billion sources. Summarized here are the results and performance. Sample completeness and purity is computed on a validation set which is adjusted to represent realistic frequencies of occurence (“class fractions”) of classes in Gaia. This reflects in particular the difficulty of identifying rare extragalactic objects among the much more dominant stars (by a factor of 103). It is shown how the performance varies with various parameters, such as magnitude and Galactic latitude. Performed are analyses of subsets of the complete set of results for sources classified with probabilities above 0.5 (and other thresholds) in the different classes, showing distributions in features, on the sky, as well as in colour–colour and colour–magnitude diagram.
