Greetings<div><br class="webkit-block-placeholder"></div><div>We have a question for the SAC users group. Recently a need to support double precision floating point for data in SEED format has been identified.</div><div>While SEED itself can support this, the problem comes with possible output formats the rdseed program should support. The most widely used</div><div>format is SAC format in our estimation.</div><div><br class="webkit-block-placeholder"></div><div>Our question is, is it possible for SAC to support double precision floating point values without loosing precision? Would it be extremely difficult to</div><div>add double precision support for SAC? Even if SAC can not support the format, would it make sense to have a double precision version of the SAC Format, if </div><div>you understand what I mean by that.</div><div><br class="webkit-block-placeholder"></div><div>One further question is, assuming that SAC and SAC format are not ready for double precision and it would be difficult to support it... what new format do you think we might consider supporting as an output format for rdseed? Do any of you have suggestions as to possible ways to deal with double precision floats as an output</div><div>format?</div><div><br class="webkit-block-placeholder"></div><div>Thanks for any help you can provide us.</div><div><br class="webkit-block-placeholder"></div><div>Cheers</div><div>Tim</div><div><br class="webkit-block-placeholder"></div><div><br><div> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div>Program Manager, IRIS Data Management System</div><div>IRIS DMC</div><div>1408 NE 45th Street #201</div><div>Seattle, WA 98105</div><div><br class="khtml-block-placeholder"></div><div>(206)547-0393 x118 </div><div>(206) 547-1093 FAX</div><br class="Apple-interchange-newline"></span> </div><br></div></body></html>
