... HST . ... Home . ... Data . ... Instrument . ... Reference Files . ... In this report, we describe recent updates to the procedures already in place for making WFPC2 dark reference files. These updates include the ability to create dark reference files by using either weekly or daily dark images as input. ... The new scripts are currently available for FTP from the WFPC2 website to users who wish to create dark reference files which are tailored to closely match the date of their HST observations. ...

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

... Just to learn how to generate a system call, I created a simple system call that basically sets and resets the value of a global parameter "PREFETCH". SYSTEM CALL code ********************************** int PREFETCH = 0; /* this is a global variable */ . ... To execute the sys_prefetch system call, I wrote a prefetch.c file with the following code. ************************code to call sys_prefetch***************** #include <linux/unistd.h> _syscall2 (int, prefetch, int, mode, int, nr_hints) . ...

... How do have my images go into a different directory? To put your images into a directory other than the standard /export/images you MUST create the directory from the dryrot prompt. ... Create the directory with the following command dryrot: mkdir /export/images/ your directory Now when you set up the directory in spicam you need to type spicam: path /export/images/ your directory This will now put the images into your directory. ...

The following are useful tcsh completions I use, which should mostly be fairly standard for any unix platform, so you can just drop them into place. # directories complete cd 'C/*/d/' complete rmdir 'C/*/d/' complete lsd 'C/*/d/' # signal names # also note that the initial - can be created with the first completion # but without appending a space (note the extra slash with no # append character specified) ...

TOOLS OF TEST GENERATION FOR SATELLITES CONTROL PROGRAMS Andrey Tyugashev, Ekaterina Myasnikova, Elena Sopchenko S.P. Korolyov Samara State Aerospace University (National Reseach University) The paper presents a research in the field of test automation for testing spacecraft control programs. ... Programmers or designers of spacecraft systems write tests manually. ... Tests are carried out by issuing the control actions on the spacecraft and condition monitoring systems parameters of the spacecraft. ...
