6. def ListOfStruct(fB: FitsBlock, col: Int = 0): List[StructField]

   Construct a list of StructField to be used to construct a DataFrame Schema.

   Construct a list of StructField to be used to construct a DataFrame Schema. This routine is recursive. By default it includes all columns.

   fB

   : (FitsBlock) The object describing the HDU.

   col

   : (Int) The index of the column used for the recursion. Should be left at 0.

   returns

   a List[StructField] with informations about name and type for all columns.

7. def ReadMyType(name: String, fitstype: String, isNullable: Boolean = true): StructField

   Conversion from fits type to DataFrame Schema type.

   Conversion from fits type to DataFrame Schema type. This can be used to set the name of a column and the type of elements in that column. Fits types nomenclature explained here: https://fits.gsfc.nasa.gov/standard30/fits_standard30.pdf

   name

   : (String) The name of the future column in the DataFrame

   fitstype

   : (String) The type of elements from the fits HEADER. See the link provided.

   isNullable

   : (Boolean) Column is nullable if True (default).

   returns

   a StructField containing name, type and isNullable informations.
