New GREGOR Infrared Spectrograph (GRIS) Data Archive – Beta Version ReleasedApril 15, 2019, from Richard Morton
The Leibniz-Institute for Solar Physics (KIS) has released a beta version of the new data archive for the GREGOR Infrared Spectrograph (GRIS, Collados et al. 2012, AN 333, 872). All GRIS data prior to 2018 are in open access and available here: sdc.leibniz-kis.de
The database contains more than 650 data sets recorded in the years between 2014 and 2017. Most of them are single raster scans recorded in spectropolarimetric mode in the 1.08µm and 1.56µm wavelength bands. Some of them are measurements in spectroscopic mode, time sequences capturing the evolution of solar features, sit and stare measurements or observation in other wavelength bands such as 2.2µm.
Currently, the user can access the archive via a web interface. Best performance is achieved using ‘Chrome’ Browser. The initial web page provides the possibility to query by various parameters such as date, wavelength, heliocentric angle, etc. The results are displayed as a list with some information and preview images. For each entry in the list, there is an additional page with detailed information such as a logfile, step size, exposure time, scan type, a preview and, if available, the position on the solar disk. The user can select one or multiple observing runs from the list and download the science ready ‘Level1’ data as a tar file.
The archive is a beta version at the moment. We invite the community to send us feedback on desired features to be implemented. Please send your comments and suggestions to email@example.com.
