FITS File Parsing Error: Keyword 'SIMPLE' Not Found - Aladin Lite Solution

This error message suggests that there is an issue with file parsing, specifically the keyword "SIMPLE" has not been found. The console may provide more details about the error. One possible reason for this error could be that the server where the file is located has not set the necessary CORS headers, which can prevent the file from being downloaded. \n\nTo resolve this issue, you can try manually downloading the FITS file from the server first. Once downloaded, you can open it in Aladin Lite by dragging and dropping the file into the application. This bypasses any potential CORS restrictions that may be causing the error.
