Doubts regarding space separated ASCII files

[Prameela Nair]

We are trying to modify the implementation for VOConvert
(http://vo.iucaa.ernet.in/~voi/VOConvert.htm) which is a tool to convert
ASCII/FITS file(s) to the VOTable format.

 

Some queries regarding space separated ASCII files -

 

1) How are null values represented? Do we add an additional space to
represent a null value for the column?

 

2) Are there space separated ASCII files where the number of spaces that
separate two values/columns is greater than 1?

   e.g. - here values for columns are separated by 2 spaces

   12  345  67  2345

   1235  234  1  265

     

 

For the fixed format files -

1) Do null values exist in fixed format files? If yes, how are they
represented?

 

 

Thanks & Regards,
