Distributed Software for Observations in Near Infrared V. Gavryusev 1 and C. Baffa Osservatorio Astrofisico di Arcetri E. Giani Dipartamento di Astronomia, Universit`a di Firenze Abstract. ... The processes denoted for control of hardware (telescope and other instruments) should be executed currently on PC dedicated for this task under DESQview/X, while all other components (user interface, tools for the data analysis, etc.) can work also under Unix. ... 1993, Di Giacomo et al. 1993). ...

Astronomical Data Analysis Software and Systems IV ASP Conference Series, Vol. ... The user interface is organized as widget­based X11 client. ... Design The design of a data acquisition package is, as always, a long struggle between many different and contrasting needs. ... 1993; Di Giacomo et al. ... In our case we have to differentiate between a number of tasks: (1) a graph­ ical user interface, (2) the display of images, (3) the hardware interface, and (4) data transfer between computers. ...

... The SF does not contain all the information required to process the ODF with the SAS. odfingest extends the SF with data extracted from the instrument housekeeping data files and the calibration database. It creates a new summary file: the SAS ODF Summary File (SOSF). ... The user need not have write access to the ODF directory. odfingest uses the parameter outdir to learn where to write the SOSF. ... Alternatively, the name of the SOSF can be passed to odfingest with the parameter summaryfile . ...

Fine Guidance Sensor Instrument Handbook for Cycle 24 > Chapter 7: FGS AstrometryData Processing > 7.2 Exposure-Level Processing . ... 7.2.2 Observing Mode Dependent Processing . ... After pipeline initialization and data quality assessments, successful observations (i.e., those that acquired the target), are processed according to the FGS observation mode: Position or Transfer. ... The corrections applied to the FGS data are as follows: . ... Transfer mode . ...

... 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. ...

... XmTel is a telescope control interface designed to to communicate with Elwood Downey's XEphem. It will also operate as a free-standing program for control of telescopes that use the NexStar, LX200 or RCOS command sets. XmTel is accompanied by routines which support the necessary communication and commands for running Meade Instruments LX200, Celestron NexStar telescopes. A version for RC Optical Systems Professional Series mounting is available from the manufacturer. ...
