First results with PISCO.
Abstract
PISCO is the acronym for the new ESO polarimeter and stands for Polarimeter with Instrumental and Sky COmpensation. The design of the instrument has been developed by K. Metz and the main principles have been published in two articles in Astronomy and Astrophysics (Metz, 1984, 1986). The instrument has been built at the Universitätssternwarte München with the technical and financial support of ESO and is now offered to visiting astronomers at the 2.2 m telescope at La Silla. This article briefly describes the instrument and first results obtained during a test run in September 1986.
