Lunar Orbiter 1 . ... The Lunar Orbiter 1 spacecraft was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions. ... The spacecraft was placed in a cislunar trajectory and injected into an elliptical lunar orbit for data acquisition. ... An 80-millimeter lens system was used to obtain Medium-Resolution (MR) photos, and a 610-millimeter lens system was used for High-Resolution (HR) photos. ...

The Lunar Orbiter 4 spacecraft was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions. ... This experiment consisted of a dual-lens camera system designed to satisfy the primary mission objective of providing photogaphic information for mapping and for the evaluation of Apollo and Surveyor landing sites. ...

... 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. ...

... The spacecraft of Magion type have been selected as the subsatellites of the Interball project: Magion-4 (C2-X) for the Tail Probe and Magion-5 (C2-A) for the Auroral Probe. ... Magion-4 was produced in the Czech Republic in collaboratrion with Russia, Ukraine, Hungary, Austria and has onboard scientific instruments and sensors designed and built in Czech Republic, Russia, Poland, Hungary, Romania, Bulgaria and Slovak Republic. ...

The previous ground processing software failed to properly trap these errors. As a result, gaps or jumps in time could occur in processed TIME-TAG data. ... All investigators working with STIS TIME-TAG data should read the more detailed discussion of possible problems, and if they believe that their data may have been affected, retrieve it again from the archive. ...

... Science . ... Science Users Information > Science Publications > Science Announcements > Processed Calibration Files for VLT instruments Now Available . ... ESO Data . ... ESOReflex data reduction workflows can be used to customize the generation of the processed and co-added calibration frames and to apply them to the science files. A detailed step-by-step guide on how to automatically associate the appropriate calibrations, raw or processed, to the science files of interest is available . ...

... The SAS_ODF environment variable shall be set to the summary file produced by odfingest , or to a directory containing the data, and access to calibration files shall be set through cifbuild . ...

Note that tracking data may not be good enough, in which case no plot is produced. omdrifthist set =/path_to_your_data/fast/tmp_tracking plotfile =/path_to_your_data/fast/P0125321001OMS002TSHPLT0000.PS trackradius =0.5 hardcopy =yes ....

Next: Running REDUCE/CCD Up: Processing the Data Previous: Processing the Data . Before any processing on the input frame is done, the REDUCE/CCD command will first collect all resources needed for the calibration of the science frame(s). These include the master calibration frames, the overscan offset, and scaling parameters. So, at this point no operations are done yet. ... As an example, suppose the science frame is supposed to corrected for dark current and to be flat fielded. ...
