How to interpret a multi-dimensional header while reading a table from a FITS format file?

edit

When reading a table from a FITS file, the Header Data Unit (HDU) contains a multi-dimensional header that provides information about the table data. To interpret this header, follow these steps:

1. Identify the dimensions: The header will typically contain information about the dimensions of the table data, such as the number of rows and columns.

2. Identify the data types: The header may also provide information about the data types for each column in the table, such as whether they are floating-point or integer values.

3. Interpret any additional metadata: The header may contain additional metadata that provides more information about the table data, such as the units of measurement or any relevant physical constants.

4. Use the information to read the data: Once you have interpreted the header, you can use this information to read the table data from the FITS file. This may involve using a specialized library or tool that knows how to read FITS files and interpret their headers.

Overall, interpreting a multi-dimensional header in a FITS file requires careful attention to detail and a good understanding of the format and structure of FITS files.
