(Figure-2 Command Toolbar)
clear - As the label implies, the clear button will clear the control console display of
accumulated spectral-line data, 25-point scan data. This function is useful if the user is
accumulating multiple spectra from different sources or galactic coordinates. The system
will treat new source spectra as additions to the accumulated spectrum.
atten - Enabling the atten (attenuation) button adds or removes a 10dB attenuation to
the receiver with successive left-button mouse clicks. The atten will illuminate red while
the 10dB attenuation is active. The attenuation value can also be read just above the
center of the message board area to the right of the power/temperature information.
Help - Clicking Help opens a window titled srthelp that contains a 6-button taskbar.
•
srt.cat -- Contains a list of keywords available to the SRT user that can be
set in the srt.cat file. A brief explanation of the keyword use is included.
•
srt.cmd -- Lists the general rules and usage of command file entries with a
few examples.
• plots
-- A Brief explanation of all the plot windows seen on the SRT console
• outputfile
-- Contains a key to reading the ASCII output of a recorded data
file
• cmdline
-- This button will show a brief list of commands used at the
MSDos prompt or Command prompt to select the desired operating mode of
the SRT.
• howto
-- Contains information about adjusting pointing, checking receiver
and antenna communication and possible adverse interaction between the
SRT program and some screen savers.
Stow - Clicking on the Stow button will return the telescope to the "normal" stow
position in the eastern-most, low-elevation position of the main Az/El travel zone. The
travel zone is established by the AZLIMIT and ELLIMIT commands in the srt.cat file.
(Assuming the SRT has been setup with the travel-zone centered on 180º azimuth)
track - The track button enables the antenna to slew to the selected source from
clicking on the map, selecting from the source list or after typing the source information
on the command entry text box. The track sequence will work automatically when a
source is selected from a command (.cmd) file.
Azel - Action on the Azel button allows the user to enter a fixed azimuth/elevation
position in the command entry text box (assuming the entered coordinates are within the
Az/El limits of travel of the SRT, as set in the srt.cat file).
