EFOSC2 Technical Reports

---

Below follows the reports on technical tests performed with EFOSC2. These reports are typically based on laboratory measurements, daytime measurements at the telescope as well as on data obtained during test and reserved nights at the telescope and other data provided by observers.

Reports with the new CCD

Full CCD Test by the La Silla Optical Detector Team (6 June, 1997)

This `report' is probably of interest only to those of you more technically inclined. The report is actually a series of plots, images and results which are the result of an automatic testing procedure.

Report on test observations IV.

Written March 13, 1997

Discusses the sensitivity of the new CCD with the various filters and grisms and the evolution of the sensitivity with time. Discusses flat-fielding, measures the instrument flexure, discusses pointing and offsetting of the telescope, measures the bias level and dark current, examines the slit profile of the movable slit, and calculates the focus offsets between the various filters.
