UVES data retrieval and processing

EsoReflex Quickstart:

1. Log in to puhti and lauch a desktop
2. Open a terminal
3. Start the uves workflow in EsoReflex by typing:
   esoreflex uves &
4. Familiarise yourself with various sections of the workflow as discussed in the lecture
5. Check the box under  “tools / animate at runtime” and change “time (in ms) to hold highlight” to 10ms
6. Run the pipeline on the demo data (that comes with the package) by pressing the play icon.

Data retrieval:

1. Log in to puhti and lauch a desktop (skip this step if you already have a desktop open)
2. Launch a browser and navigate to the ESO archive. Input the name or co-ordinates of your target (**). Familiarise yourself with the various parameters such as the search box, instrument, data product type etc.
3. Request data for your target and associated calibrations (not master calibrations)
4. Note that if you do not already have an ESO portal account, you may have to create one to enable data download.

** You may pick any target of your choice.

Data processing with esoreflex

1. In a terminal create a logical directory structure to store the raw (the ones that you just downloaded) and reduced files. Example:
   cd
   mkdir target_name
   cd target name
   mkdir uves
   cd uves
   mkdir raw
   mkdir reduced
   cd raw
   mv ~/Downloads/<filename> .   (note the “dot” at the end! “filename”= file downloaded from the archive)
   gunzip *.Z             (uncompress the files; this command depends on the format)
2. Launch esoreflex and the uves workflow
3. Change the input and output directories in esoreflex to reflect the location of the raw data files and the output directory (“reduced”).
4. Repeat step 5 from the quickstart section at the start of this page
5. Run the pipeline and have a go and changing various parameters e.g. extraction width, cosmic ray removal parameters etc.
