RU(N) - The primary exposure command

Perform a run, always into a new file:-

1. Check telemetry
2. Clear the chip unless NOCLEAR flag is set.
3. Pre-flash if non-zero pre-flash time is set.
4. Expose (open shutter, time exposure, close shutter)
5. Read out chip.
6. Reset the pre-flash time to the default.
7. Display data on Lexidata.
8. Write data to selected dump device as FITS image.

Parameters

As for GLANCE, the exposure time in seconds, prompted for if omitted.

The object name can be given as a second parameter. It should be in double quotes and will be prompted for if omitted.

Note that for runs of less than 10 secs the run will not start unless you respond to the prompt for the name.

Examples

Adam:> RUN 1000 ``LMC Abnormal Refraction''

Perform a 1000 second run looking at the LMC.

Notes

You can change your mind about the exposure time while the run is in progress by using the command TIME, or STOP at the appropriate moment.

During all but the briefest runs, the ADAM terminal is available for displaying the RUNSTATus, PAUSEing, CONTINUEing, STOPping, ABORTing and running application programs, but you may NOT use the TELE command during a run.

All runs are timed using the Time Service, and although the actual exposure time may not be exactly that which was requested, the actual exposure time will be known to about a millisecond accuracy and accurately recorded for you.

If the exposure time is zero, then as for GLANCE, the shutter is not opened at all. This is used when taking bias frames:

ADAM:> RUN 0 ``Zero Bias Frame''
