A VLT spectrum of EROS-BLG-2000-5

This chart shows a spectrum of EROS-BLG-2000-5, obtained with the FORS1 multi-mode instrument at the 8.2-m VLT ANTU telescope at Paranal on June 25, 2000, before the second caustic crossing described in the text. A small part of the spectrum around the H-alpha line at wavelength 656.2 nm is enlarged in the insert.

Technical information: The FORS1 spectrum shown here is a composite of 300-sec exposures taken with with the 600B (spectral interval 390 - 580 nm), 600R (538 - 753 nm) and 600I (705 - 918 nm) gratings; the insert covers a 10 nm wide region near H-alpha.
