Requirements Checklist

Requirement Description Done? Date Updater
Antenna Steerable
The antenna must be steerable and capable of pointing and tracking a given (Az,El) direction at
sidereal rates.
Yes
2007/02/01
Ralph Marson
Record Time-Stamped (Az,El)
The antenna must be capable of recording time-stamped Az-El coordinates during position tracking.
Yes
2007/02/10
Ralph Marson
OPT Signal Multi-Availability
The OPT signal must be available both to the monitor and control system and any real-time monitoring systems (such as video monitors in the ATF Control Building).
Yes
2007/02/10
Ralph Marson
OPT M&C Points Available
It must be possible to access all OPT monitor and control points from either a command line or a
GUI.
Yes
2007/01/24
Ralph Marson
OPT Focus Control
It must be possible to make real-time changes to the OPT focus and monitor the effect of those changes on a video monitor.
Yes
2007/01/24
Ralph Marson
Daytime Observations
It should be possible to perform daytime observations with the OPT using the IR filter.
Yes
2007/02/16
Jeff Mangum
Antenna Offset Positioning
It must be possible to command the antenna to perform offset positioning using both the Mount GUI and from a script.
Yes
2007/02/15
Jeff Mangum
Spirograph
It should be possible to command the antenna in a spiral pattern.
Yes
2007/02/15
Jeff Mangum
Log Messaging of Position Corrections
Log messaging should indicate magnitude of position corrections due to precession and pointing
model.
No
 
 
All TPOINT Terms Available
All possible pointing model terms available within the TPOINT analysis package (and the tcspk pointing kernel) must be available for inclusion in the online pointing model.
No
 
 
Write TPOINT Files
The Computing IPT software must be capable of writing a properly-formatted TPOINT star position file which allows for proper analysis of OPT pointing measurements.
Yes
2007/04/15
Jeff Mangum
Set and Query Pointing Model Terms
It must be possible to set and query the current pointing model terms in use.
Yes
2007/02/14
Jeff Mangum
Dump Star Centroids at >= 1 Hz
Must be able to dump derived star centroid (Az,El) positions to an ASCII text file at rates of at
least 1 Hz (faster would be better).
No
 
 
Star Selection GUI
Must be able to select a list of several hundred stars with appropriate criteria (lying within specified magnitude, LST, elevation, and time ranges, isolated, etc.) from the Tycho2 database. This selection should be done with a simple GUI which allows for target list editing before submission. A model for this tool would be the “Tycho” GUI developed for the AEG testing.
No
 
 
The Dreaded Manual Mode
It must be possible to perform OPT measurements in “manual mode”, independent of the scheduling software.
No
 
 
Manual Mode Writes to Archive
Manual mode observations must write data to the archive to be accessible for later analysis.
No
 
 
Manual and Automatic Mode Writes ASCII
Manual and automatic (using the scheduling software) mode observations must write data to a simple ASCII file for simple data quality investigation.
No

Weather Data
Automated VLA weather (P,T,RH) input into M&C system.
Yes
2007/04/20
Jeff Mangum

Fix default TAI2UTC setting at M&C level. Currently automatically set to 33 sec. Should be 0.
Yes
2007/03/05
Ralph Marson

Write target (Az,El) to logs for debugging access.
Yes
2007/04/01
Jeff Mangum

Write correct (Az,El) values to TPOINT file.
Yes
2007/04/15
Jeff Mangum
Out-of-Range Position Behaviour
When the Mount receives a commanded position out-of-range, should just skip to next star.
No
 
 
On-Source Criterion
Should be within position tolerance in both coords for at least 3 TEs before starting to collect frames.
No
