and follow prompts. Note that it is most efficient in terms of observing time to put data onto DISK only, and save it on TAPE later using FITSOUT. This can be done during long (> 300 second integrations) so that is perfectly possible to have all your data safely dumped to tape by the end of the night. The EAGLE disk can theoretically hold more than 1200 CCD frames which is more than adequate in most cases for a week's observing. However you are strongly recommended to dump to tape as soon as convenient. Power cuts have drastic effects on large disks.
Initialise the filter wheel by typing ZEROSET in response to an Adam:> prompt.
Cryostat filled and cold?
Correct filters, filter wheel, optical thicknesses
Chip orientation correct?
Telescope pointing checked, SNAFU?
Telescope in focus? (FOCUS, SETFOCUS)
MIMIC display active?
Adam:> FILTER <name>
Adam:> FILTER? (displays which filter position is in beam)
Adam:> GLANCE (sec)
This run can be saved with
Adam:> KEEP ``HD123 10 SECs V FILTER``
Adam:> RUN (sec)
This command makes the exposure, reads out the chip, displays the image on ther Lexidata with auto-scaling and saves the image file on disk, tape or both, depending on the option chosen. Useful commands during RUN are RUNSTATUS to tell you how long to go; STOP, which terminates and saves normally, just as if requested time had expired; ABORT, which closes the shutter, and loses the data and TIME (sec) which resets the requested exposure time and PAUSE (to stop exposure temporarily) and CONTINUE (to restart a PAUSEd exposure).
Follow instructions/indications on the Lexidata and the joystick box. To display and examine other runs:
Adam:> DISP R(run number)
Some on-line analysis is available; see II.4. For general file-handling see II.5.
Adam:> FITSINIT (follow prompts - for new tapes only - do not use on tapes which already contain data)
Adam:> FITSOUT (follow prompts)
Dumps from disk to tape with verify option selected take about 50 seconds so it is convenient to write a few at a time during long exposures.
You can make your data safe by
(i) Using the VERIFY option on FITSOUT and
(ii) dismounting the tape from the deck and removing the write ring.
Please place completed D tapes in the tray marked ``FOR DUTY OFFICER COLLECTION'' together with a copy request form giving details of what is required. Duly copied C tapes for your use will appear in the TAPES COPIED pigeon hole in the INT building on the first floor together with a short listing of the tape contents. Please note that IT IS STRICTLY FORBIDDEN FOR OBSERVERS TO TAKE D-TAPES FROM THE MOUNTAIN.
