[<I>sbigfile</I>]

<H2 id="description">DESCRIPTION</H2>

<p>This program is part of <a href="index.html">Netpbm</a>.

<p><b>sbigtopgm</b> reads an image file in the native format used
by the Santa Barbara Instrument Group (SBIG) astronomical CCD cameras,
and produces a PGM image as output.  Additional information on SBIG
cameras and documentation of the file format is available at the Web
site, <A HREF="http://www.sbig.com/">http://www.sbig.com/</A>.

<p><b>sbigtopgm</b> recognizes some variation on the documented SBIG Type 3
format.  It allows any capitalization in the header.  It ignores all
whitespace in the header except newlines.  So a header line can end in
newline, CRLF, or the bizarre LF-CR actually required by the spec.
