EIS Deep Survey Reports from the EIS Team HOME INDEX SEARCH HELP NEWS

Discrepancy detected between the astrometry of the optical and infra-red pass bands. The initial astrometrical solution was affected by the very small number of stars in the field.
The infrared data were reduced using the Jitter program of the Eclipse image processing package. It has been reported that magnitudes computed using this program may be underestimated by about 0.15 mag at faint magnitudes.

EDS_2.2 (09 May 2001):

The released weight maps for the SOFI observations have been found to be corrupted.The corrected image packages will be realesed soon. We apologize the users for this inconvenience.
After the data release, A. Cimatti, E. Giallongo, E. Daddi, P.Saracco, C. Lidman and P.Rosati have reported to the EIS Team that a systematic offset was present at faint magnitudes between the released Infrared data and their independent photometry in the Chandra Deep Field South. Their warning has prompted a through check of the procedure and a typo was indeed found in the reduction program.
