Direct Data Retrieval (by File)

Do you want to retrieve a list of files?

This form is intended for users who know the file names or identifiers of the data files they want to retrieve from the ESO Science Archive Facility.

Input:
A list of ESO archive files (up to ).
Note: ORIGFILE names are not supported.
Refer to the Supported formats and file types box at the bottom of this page.
You can choose how to provide your list:
  • at the top, typically used for a handfull number of files, you can paste a list of files in the text area, and then click the "Submit" button;
  • at the bottom, you upload a file containing the list of files you want to retrieve: as soon as uploaded, the list will be automatically submitted.
In both cases you'll be brought to the Download Portal interface where you will be able to choose some options:
  • authenticate in case you need to exert your access permissions
  • choose the method of download (zip, script, etc)
  • request additional related files: calibration files (raw or processed) needed to process the raw data, ancillary files of a product, products generated from the requested raw data (if any), etc.

Supported input formats and file types

Since 2026, this service supports all retrievable file types (as an example, phase 3 ancillary files were previously not supported).

File names and identifiers are case-sensitive. The file extension of FITS files (e.g., .fits, .fits.fz, .fits.Z, .tfits, etc.) if provided is discarded. The file extension of any other file is mandatorily required (e.g., .TAR).

You would normally provide one file name/id per input line.
On each line, any text after a # is considered a comment and discarded.
It is also possible to copy paste the content of a FITS header containing the desired files, as in this example:

PROV1   = 'OMEGA.2015-05-20T01:11:44.489.fits' / Originating science file
PROV2   = 'OMEGA.2015-05-20T01:15:28.750.fits' / Originating science file
PROV3   = 'OMEGA.2015-05-20T01:19:13.140.fits' / Originating science file
PROV4   = 'OMEGA.2015-05-20T01:22:57.512.fits' / Originating science file
PROV5   = 'OMEGA.2015-05-20T01:26:41.762.fits' / Originating science file
