Functionalities

Archive search

The GTC Archive, at CAB (INTA-CSIC), is accessed by means of a web-based fill-in form which permits queries driven by a set of conditions. The form is divided into the next sections:

Target list

A list of targets may be provided in the form of coordinates or object names, one line each. If the object name is provided the system will automatically resolve the corresponding coordinates using the SIMBAD database. The search radius around each of the coordinates may be specified.

These searches are made using pgsphere in the database.

To ease the search of a certain product, product ID numbers may also be provided to perform the search.

Date

A range of dates may be given to filter the results. By default the dates of the first and the last registered product are provided to perform a search without date restrictions.

Instrumentation

A list of all instrument and modes are available to check/uncheck.

Program

Specific programs and observing blocks may be selected. Character '%' may be used as wildcard. In the example above, the user is interested in data of the 10A semester.

Order

This field is used to specify the order in which the results are displayed. The results may be ordered by observing date, instrument or program/OB.

Pages

The results may be returned in blocks of 10, 50 or 100 results per page. If more than one page is returned, a specific number of page may be selected to be displayed. By default, the first page of the results is shown.

Result from search

The following image shows the typical output obtained after querying the archive.

The number of scientific products found matching the search criteria is given. If there are more than one page of results, the "Next" and "Prev." links may be used to navigate among them.

The scientific products found are presented in a table where, for each of them, the following information is shown:

Four different blocks are available to access the data details and to download the data products. In all of them checkboxes exist to download several products at a time, compressed in a ZIP file or in TAR.GZ file, using the "Download Selected" button:

In the next sections the different blocks of the page of results are described.

Raw Data

This block gives access to the scientific products. Data can be downloaded or visualized using ALADIN. FITS headers can also be visualized by clicking on the corresponding link.

Calibration Files & Acquisition Images

For each of the scientific products, the associated set of calibration files and, if it is the case, acquisition images, may be downloaded or previewed. The "view" option will show a page with detailed information. Each calibration file may be previewed using ALADIN or downloaded. It is also possible to preview several files at a time using ALADIN. To do so, several files may be selected and then ALADIN launched using the "Preview Selected" button.

The files marked in yellow are identified to have any kind of warning detected by the GTC Quality Control at CAB. The associated message is shown by clicking the product ID number.

For those modes having acquisition images, the same functionalities as for calibration files are available.

QC Files

If warnings have been detected by the GTC Quality Control System for any of the associated files of the scientific product, a log containing that information may be accessed or downloaded. Detailed information can be found by clicking the "View" button:

Download File

In the Download file you have the data you have selected organized by folders:

Reduced data upload

The system provides a simple way to upload reduced data for those users with the right privileges. To access the reduced data upload module, select "Upload reduced data" in the main page of the archive.

If the user is not already logged in, the system will prompt a login window.

The procedure to upload reduced data is very simple. Only two fields have to be provided: the data collection name (typically associated to a paper) and the file containing the reduced data.

STEP I: Creation of a new data collection.

There are three mandatory items that have to be specified when creating a new data collection: data collection name, publication bibliographic code and reduction type. Every collection is associated to the publication where the reduced data have been published and its bibliographic code has to be given. For the reduction type, predefined reductions may be selected or free text may be added to express a reduction type not present in the page.

STEP II: Data upload.

The reduced data may be uploaded in several formats. The user may provide a single FITS file (FITS.gz is also admitted) or, if more than one file is going to be uploaded, he/she can use tar, tar.gz or zip to submit the collection of FITS files. All the files uploaded in this action will be associated to the selected data collection. In case the user needs to create a new data collection, the button "New Collection" may be used and a page to create a new data collection will be prompted.

STEP III: Results of the upload.

When the data upload has been committed, a page will present the result of the upload.

The number of files correctly uploaded will be given, as well as the number of files where problems were found. For the problematic files, the reason of the failure is expressed both with a color code and with a detailed description. Those files showing orange color had been already uploaded in the past and cannot be uploaded again. Files showing red color have raised any kind of problem and cannot be ingested in the archive. Should you need any help with this, please, do not hesitate to contact GTC archive staff (gtc-support@cab.inta-csic.es). Files uploaded without problems, and thus not present in the error log, are ingested in the archive automatically and available for the community through the archive search functionality.
