NAME

       ConvertType - convert known data types to each other

SYNOPSIS

       astconvertt [OPTION...] InputFile1 [InputFile2] ... [InputFile4]

DESCRIPTION

       ConvertType  is part of GNU Astronomy Utilities 0.22.  ConvertType will convert any of the
       known input formats to any other of the known formats. The output file will have the  same
       number of pixels.

       For  more  information, please run any of the following commands. In particular the second
       contains a very comprehensive explanation of ConvertType's invocation: expected  input(s),
       output(s), and a full description of all the options.

       All options and their values:
              $ astconvertt -P

       Inputs/Outputs and options:
              $ info astconvertt

       Full section in manual/book:
              $ info ConvertType
