... The first of the equations defines the position of the spectral orders, m , in the raw image, while the second equation gives, for each order, the dispersion relation in one dimension. ... where the coefficients are computed using least squares techniques on a grid , i.e. sample number and line number of points located within the spectral orders of the image. These points in the grid are found automatically by an order--following algorithm, normally using the FLAT or STD image. ...

Next: *.imh and *.qp Extensions Up: IRAF/PROS Files Previous: IRAF Image Arrays . The x-ray data are stored in QPOE files (Quick Position-Ordered Events, *.qp ) rather than image arrays. ... Note that, unlike IRAF images, QPOE files have no associated header file, and are always stored in the current directory, unless explicitly specified otherwise.

RTT150 . ... The primary mirror 1 reflects light to the secondary mirror 2 which sends the converging beam of light to the system of four flat mirrors 3, 4, 5 and 6. That allows the beam of light to leave the telescope strictly along its polar axis and be collected in Coude focus. ... That's why at any tube position (for any rotation along the declination axis) beam of light parallel to the principal axis after reflection on mirror 3 follows the direction of declination axis. ...
