- Click on Output Options, which is in a yellow box on the right-hand side of the other query modes row along the top. A new browser tab will open.
- Set the Output Format in the top row.
- Choose ASCII (;-separator for spreadsheet) from the drop-down menu.
- Check file output.
- Make changes to the List Display column.
- Make sure Identifier is checked.
- Make sure Fluxes/Magnitudes is checked
- You must also check the individual filters in the right-hand cells of the Fluxes/Magnitudes row. You have nothing to lose by clicking all of them.
- In general, uncheck all other rows, unless you are suspicious about your target list and would like some extra columns in your spreadsheet to act as a reality check.
- Click the SAVE button at the bottom to set a browser cookie and save your changes.
- Query a List of Identifiers is on the bottom half of the original SIMBAD query browser tab.
- Prepare a .txt Notepad file containing only SIMBAD acceptable identifiers without a header. Chances are if you got your list of identifiers from a catalog, you'll be okay.
- Click Choose File and browse to your text file.
- Check list display.
- Check Submit File.
- A .csv file will begin downloading automatically.
- Since semicolon is not the default delimiter in Excel, either use File > Open and then Data > Text to Columns, or use Data > Import External Data > Import Data.
- The first few rows of the file identify and timestamp the query
- Missing magnitudes for a given filter are shown with a tilde (~) symbol.
- Identifiers from the uploaded list that SIMBAD couldn't parse are listed separately at the end.
