Methods Documentation

get_headers(product_ids, cache=True)[source]¶

Get the headers associated to a list of data product IDs

This method returns a Table where the rows correspond to the provided data product IDs, and the columns are from each of the Fits headers keywords.

Note: The additional column 'DP.ID' found in the returned table corresponds to the provided data product IDs.

Parameters

product_idseither a list of strings or a Column: List of data product IDs.

Returns

resultTable: A table where: columns are header keywords, rows are product_ids.

list_instruments(cache=True)[source]¶

List all the available instrument-specific queries offered by the ESO archive.

Returns

instrument_listlist of strings
cachebool: Cache the response for faster subsequent retrieval

list_surveys(cache=True)[source]¶

List all the available surveys (phase 3) in the ESO archive.

Returns

survey_listlist of strings
cachebool: Cache the response for faster subsequent retrieval

login(username=None, store_password=False, reenter_password=False)¶

Login to the ESO User Portal.

Parameters

usernamestr, optional: Username to the ESO Public Portal. If not given, it should be specified in the config file.
store_passwordbool, optional: Stores the password securely in your keyring. Default is False.
reenter_passwordbool, optional: Asks for the password even if it is already stored in the keyring. This is the way to overwrite an already stored passwork on the keyring. Default is False.

query_apex_quicklooks(project_id=None, help=False, open_form=False, cache=True, **kwargs)[source]¶

APEX data are distributed with quicklook products identified with a different name than other ESO products. This query tool searches by project ID or any other supported keywords.

Examples

>>> tbl = Eso.query_apex_quicklooks('093.C-0144')
>>> files = Eso.retrieve_data(tbl['Product ID'])

query_instrument(instrument, column_filters={}, columns=[], open_form=False, help=False, cache=True, **kwargs)[source]¶

Query instrument-specific raw data contained in the ESO archive.

Parameters

instrumentstring: Name of the instrument to query, one of the names returned by list_instruments.
column_filtersdict: Constraints applied to the query.
columnslist of strings: Columns returned by the query.
open_formbool: If True, opens in your default browser the query form for the requested instrument.
helpbool: If True, prints all the parameters accepted in column_filters and columns for the requested instrument.
cachebool: Cache the response for faster subsequent retrieval.

Returns

tableTable: A table representing the data available in the archive for the specified instrument, matching the constraints specified in kwargs. The number of rows returned is capped by the ROW_LIMIT configuration item.

query_main(column_filters={}, columns=[], open_form=False, help=False, cache=True, **kwargs)[source]¶

Query raw data contained in the ESO archive.

Parameters

column_filtersdict: Constraints applied to the query.
columnslist of strings: Columns returned by the query.
open_formbool: If True, opens in your default browser the query form for the requested instrument.
helpbool: If True, prints all the parameters accepted in column_filters and columns for the requested instrument.
cachebool: Cache the response for faster subsequent retrieval.

Returns

tableTable: A table representing the data available in the archive for the specified instrument, matching the constraints specified in kwargs. The number of rows returned is capped by the ROW_LIMIT configuration item.

query_surveys(surveys='', cache=True, help=False, open_form=False, **kwargs)[source]¶

Query survey Phase 3 data contained in the ESO archive.

Parameters

surveystring or list: Name of the survey(s) to query. Should beone or more of the names returned by list_surveys. If specified as a string, should be a comma-separated list of survey names.
cachebool: Cache the response for faster subsequent retrieval

Returns

tableTable or None: A table representing the data available in the archive for the specified survey, matching the constraints specified in kwargs. The number of rows returned is capped by the ROW_LIMIT configuration item. None is returned when the query has no results.

retrieve_data(datasets, continuation=False, destination=None, with_calib='none', request_all_objects=False, unzip=True)[source]¶

Retrieve a list of datasets form the ESO archive.

Parameters

datasetslist of strings or string: List of datasets strings to retrieve from the archive.
destination: string: Directory where the files are copied. Files already found in the destination directory are skipped, unless continuation=True. Default to astropy cache.
continuationbool: Force the retrieval of data that are present in the destination directory.
with_calibstring: Retrieve associated calibration files: ‘none’ (default), ‘raw’ for raw calibrations, or ‘processed’ for processed calibrations.
request_all_objectsbool: When retrieving associated calibrations (with_calib != 'none'), this allows to request all the objects included the already downloaded ones, to be sure to retrieve all calibration files. This is useful when the download was interrupted. False by default.
unzipbool: Unzip compressed files from the archive after download. True by default.

Returns

fileslist of strings or string: List of files that have been locally downloaded from the archive.

Examples

>>> dptbl = Eso.query_instrument('apex', pi_coi='ginsburg')
>>> dpids = [row['DP.ID'] for row in dptbl if 'Map' in row['Object']]
>>> files = Eso.retrieve_data(dpids)

verify_data_exists(dataset)[source]¶: Given a data set name, return ‘True’ if ESO has the file and ‘False’ otherwise
