TL;DR: In this article, Chandra observations of two flanking fields (FFs) in Orion, outside the Orion Nebula Cluster (ONC), were taken with the ACIS-I camera with an exposure time of about 48 ks each field.
Extending the ICRF into the infrared: 2MASS-UCAC astrometry
TL;DR: An external comparison between the infrared 2MASS and the optical UCAC positions was performed, both being on the same system, the ICRS as discussed by the authors, and about 48 million sources in common were identified.
