... Plate reductions are necessary to measure the parallax, proper motion, and reflex motion of a given object with respect to the reference field star. ... The plate overlay tool derives a virtual plate using either a four parameter or six parameter plate solution. ... Formally the six parameter model requires at least three common reference stars in each plate, but in order to avoid over-constraining the plate solution, you should not apply the six parameter model with fewer than five reference stars....

... As part of the development of a new Python-based CL for IRAF tasks by the Science Software Group at STScI, we have developed a GUI-based parameter editor for IRAF tasks using Tkinter. This new parameter editor is intended to provide the equivalent functionality of the IRAF EPAR task, but to make parameter editing easier by using appropriate user interface elements, such as menu choice lists, action buttons, and file browsers. ... Figure 1: The GUI-based Python/Tkinter IRAF task parameter editor. ...

The magnetic mapping is fulfilled by the magnetic field line tracing from the satellite position up to the Ionosphere (stop trace at the altitude 110 km). ... As a rule the Tsyganenko [1987] external magnetic field model and IOPT = 3 (Kp = 2) are used. ... The output file includes the following information: . ... For example the file with name aa9610d1.geo contains the information corresponding to the aposteriory magnetic mapping for INTERBALL Auroral Probe for the first decade of October 1996. ...

Next: Echelle Reduction Method Up: No Title Previous: Example . This Chapter provides the basic information necessary to understand the echelle љ package implemented in MIDAS . ... Tutorial examples are available in the system (command TUTORIAL/ECHELLE ) and are also included in the Appendix so that users without previous experience in MIDAS could become familiar with the calibration procedures. ... The methods described here are generally sufficient to cover a wide range of echelle formats. ...
