... The Multiple Extension FITS (MEF) file interface is an IRAF library providing facilities for general file operations upon FITS multi-extension files. ... The Multiple Extensions FITS (MEF) interface consists of a number of routines to mainly read a FITS Primary Data Unit or an Extension Unit and manipulate the data at a file level. ... Read the FITS header of a MEF file that matches the EXTNAME or EXTVER keyword values or if not specified, read the extension number `group'. ... The header filename. ...

... Specs . ... Data in folding and search modes will be output as FITS files. The DFB also has a mode that provides digitized baseband output suitable for the next generation of real-time coherent dedispersion systems. ... The output file will be a standard, pulsar folded profile with full polarisation and a given number of phase bins, frequency channels and subintegrations. ... The DFB is specified to allow 2048 frequency channels and 2048 phase bins for a 4-ms pulsar recorded with 8-bit sampling. ...

It is now possible to specify multiple log files, each with a fully customizable format. ... Multiple log files are implemented as part of the mod_log_config module which as of Apache 1.2 is the default log module. Multiple log files be created with either the TransferLog or CustomLog directive. These directives can be repeated to create more than one log file (in previous releases, only one logfile could be given per server configuration). ... Syntax: CustomLog filename "format" . ...

The winds would be much stronger. ... In using what-if questions in the classroom, it is worth bearing in mind that students extrapolating the effects of new scenarios will encounter two different situations: direct changes to the new version of Earth and indirect changes resulting from the direct changes. ...

Jupiter's Europa Harbors Possible "Warm Ice" or Liquid Water . Tantalizing new images of Jupiter's moon Europa from NASA's Galileo spacecraft indicate that "warm ice" or even liquid water may have existed, and perhaps still exists today beneath Europa's cracked icy crust. ... This shows the ice crust has been or still is lubricated from below by warm ice or maybe even liquid water." ... We are interested in identifying the time and places on Europa where liquid water might exist. ...
