Luminance



If the unit is one magnitude, it applies to a star of that faintness, covering (defocused) a solid angle of:

save settings    name='mydefault' value='True'> use my saved settings

Another option is to use your own command line (ev. name='override' value='True'> overriding all previous data):

(`?' gives help). 

';
 echo system(EscapeShellCmd("/home/jhollan/bin/".$para) .
  "| sed 's/>/\>\;/g ; s/
 
";
 echo 
'
 The result you got from the programme 

lum (available as a part of a package 

pas_jh.zip (1.2 MB) --
the needed unit str_num.pas is unzipped within 
this directory, the whole tree of my programmes within

this directory)

 with a command line: 
' ;
  echo EscapeShellCmd($para)  ;
  echo "
 " ;

# saving the settings:
if ($save) 
 {
  foreach ($varsS as $v) 
    { if ($$v!=="") { setcookie("c$v", $$v, time()+3E7); }
     } 
  }
