... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

XMM-Newton OM Response Files Page . ... Data Analysis SAS News What is SAS? ... The response files have the name om_effarea_<filter>_v2.0.rsp. The response files should be used in conjunction with a spectral data file containing the filter count rate. Such a data file may be created by editing the template filter file om_filter_default.pi with a fits editor such as 'fv' and changing the "RATE" and "STAT_ERR" entries in the SPECTRUM extension to the filter count rate and error. ...

. Filter wheels currently only hold 2 inch (50mm) square filters . The database is of all shared Apache Point Observatory Filters. Requests for filters are made through the Chief Telescope Engineer or a 3.5-m Observing Specialist. APO Filters Inventory Database .

... MOTIVATION !Operations at observing sites should have quick and reliable access to the data, therefore observing sites are provided with their own local database server. ... SERVICE MODE OPERATIONS Standard service mode operations: !OBs produced by investigators are submitted to Garching. ... OBs moved to the operational database at Garching are replicated to the operational database at the observing sites by the same mechanism used for standard service mode Obs. ...

... Apache HTTP Server Version 2.2 . ... This document describes the use of filters in Apache. ... The Filter Chain is available in Apache 2.0 and higher, and enables applications to process incoming and outgoing data in a highly flexible and configurable manner, regardless of where the data comes from. ... A wider range of applications are implemented by third-party filter modules available from modules.apache.org and elsewhere. ... There are two ways to use filtering: Simple and Dynamic. ...
