I often have to parse such astronomical data. I think you have to get your hands dirty. I try to keep it simple as possible: 
#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

# hash for data
my $data = {};

# array of column names
my @cols = ();

for (<DATA>) {

  # normaliize the data
  next if /^\s/ or /^Annular/;
  
  if (/^Site/) {

    # grab column titles, minus the key (Site)
    @cols = map {$_} split /\s+/; shift @cols;
  }
  elsif (/\S+/) {

    # parse column data
    my @line = /
    ([A-Za-z ]+)\s+      # Site
    (\S+\s+\S+)\s+       # Longitude
    (\S+\s+\S+)\s+       # Latitude
    (\S+)\s+             # Elvn
    (\S+\s+\S+\s+\S+)\s+ # U.T.
    (\S+)\s+             # PA
    (\S+)                # Alt
    /x;
    
    # clean the key
    my $site = do { $_ = shift @line; s/\s+$//; $_ };
    next unless $site;
    
    # map titles to data
    my %line = do { @_{@cols} = @line; %_};
    
    # add to hash
    $data->{$site} = \%line;
  }
}
# tada
print Dumper $data;
