When Apache starts, it connects to some port and address on the local machine and waits for incoming requests. By default, it listens to all addresses on the machine, and to the port as specified by the Port directive in the server configuration. ... There are two directives used to restrict or specify which addresses and ports Apache listens to. ... Listen can be used to make a single Apache server listen to more than one address and/or port. ... Syntax: Listen [ port | IP-address:port ] . ...

Fabry-Perot data cubes. Introduction: what is "data cubes"? Observations with the IFP consist of successive acquisition of a few dozen images of interference rings from the object (or from a calibration lamp) when changing the optical path between the flat-parallel plates. The radius of the rings is a function of wavelength and gap between the plates of the interferometer. ... Its interference rings of Ne line which use for phase calibration (convert object data to wavelength-scale). ...
