Background
This web page gives information regarding the ESI MIRA software for
checking telescope focus.
Procedure
As of mid-2010 the ESI software has changed and is unable to retrieve
the value of PMFM directly from ACS. This means that MIRA must be
launched in a particular way by the OA in order to work:
- From DCS GUI, click Instr > ESI > current to
bring up the ESI Operations Menu on the current screen.
- Click on the menu and release on malacq.tcl to launch
the malacq tool.
- Click on the menu and release on Mira to launch
the Mira analysis tool.
Components
The following pieces of software are relevant in the running of the
MIRA procedure for ESI. Note that all software runs under the
esieng account on esiserver.
- /home/kanaha/esieng/bin/malacq.tcl: Script for acquiring
the MIRA images. This is actually a symlink to miracq.tcl
(which is in turn a symlink to the current version).
- /home/kanaha/esieng/bin/cshow.malacq: Starts a "cshow"
process covering all of the CCD keywords changed by
malacq.tcl. Output to /kroot/log/malacq.log.
- /home/kanaha/esieng/bin/tailMalacqLog: Tails the file
/kroot/log/malacq.log to keep tabs on the procedure.
Data Directory
All ESI Mira image are written to the directory /s/sdata701/malign.
