** OPT image check [#i2744578]
*** Display an optical image [#f3f9226e]
+ Start an observation table (table with name starting with 't', e.g. 't163-16C.start'), which will just point the telescope to a star and keep tracking it
-- CSV lead will instruct the observation table to be used in Observing Log.
+ Login to the Mitaka analysis computer (e.g. aste-ms1) with asteXX (e.g. aste16)
 % ssh -Y asteXX@aste-ms1
-- Don't forget to add '-Y' option to forward windows.
+ Initialize the video capture board (at the start of measurements once a day)
 asteXX@aste-ms1: ~/analysis/bin/optinit.sh
 * ping aste-c1c
 * ssh astecntl@aste-c1c /cosmos3/naoj/sbinSol/optinit
 device:    [ ok ]
 mmap:      [ ok ]
 init bcr:  [ ok ]

+ Display (a part of) an optical image
 asteXX@aste-ms1: ~/analysis/bin/optshot.sh r  1  128
                                           (1)(2) (3)
 (1) Frame color to be dumped (normally, 'r'=Red is used)
 (2) Number of frames to be taken (set '-1' for infinite loop)
 (3) Image size [pixel] (set '448' for a full-size image)
 This will display an image whose center is (256, 256) pixels and size is 128 pixels.
 NOTE pixel scale is 1.27 [arcsec/pixel].
#ref(opt_optpon.png)
-- A star would be close to the image center, if antenna pointing is appropriately adjusted.
+ Stop the running observation

*** Adjust focus position [#fe8f117c]
+ Run a observation table just tracking a star
 group: asteXX
 project: opttrk
 observation table: Select a table close to the current LST
 e.g.) t132-36B.start for LST13h
        (1)(2)(3)
 (1) R.A.
 (2) Dec.
 (3) Brightness (A>B>C>D)
     夜間Aの星はサチる可能性がある
+ Display (a part of) an optical image
 asteXX@aste-ms1: ~/analysis/bin/optshot.sh r -1  128
                                           (1)(2) (3)
 (1) Frame color to be dumped (normally, 'r'=Red is used)

 This will display an image whose center is (256, 256) pixels and size is 128 pixels.
 NOTE pixel scale is 1.27 [arcsec/pixel].
+ Login to aste-c1c with astecntl
 > ssh astecntl@aste-c1c
+ Connect the stage controller
 astecntl@aste-c1c: tip serial2
 connected    <--- confirm this message for successful connection
+ Move the focus stage so as to achieve sharp image in OPT

** Troubleshooting [#s6cde231]
- Cannot login to aste-c1c
-- Visit [[Trouble Shooting]].
- Cannot initialize the capture board or take optical images
-- TBD
- No star in an optical image
-- Make sure no auxiliary offset in dAZ and dEL. That is (dAZ, dEL) = (0.0, 0.0).
-- Move the focus stage.

- Connection failures to the focus stage controller
-- aste-c1cをrebootした直後は接続に失敗する場合が多いので、以下の対症療法を試してみてください(ほぼ百発百中)
++ rootになる
++ admintoolを立ち上げる
++ 「シリアルポートの設定」を選び
++ term/2を選び、(ダイアログが開く)
++ 設定変更をしないでOKボタンを押す (あるいは、適当に設定をいじるが最後は元に戻しOKボタン)
-- all ports busyが出た場合は tip のprocessをkillすることでも大丈夫
==>要確認
-- キャビン(前室)に行って、ステージの電源を入れ直す (ラックの裏側のケーブルがやたらととぐろを巻いている中に、「光望遠鏡タップ」とか書いたケーブルがあり、100Vに差してあるはず。これを抜き差しすればよい)
-- 電源を切ってもステージ位置は保存されます (ただしQ:1を送ったときに帰ってくる位置値は0になる。すなわち、原点(位置値=0)は、電源が入った時点でステージがあった位置に設定されてしまう←仕様)

- Focus stage: status error / command error
 Q:1
 
 1,         0,X,K,R

コマンド入力の際、ステータスを読んでからパルス値を入力する前にリターンを２回押していない可能性がある。

- Focus stage: cannot display the status
 Q:1
 
一度 ''"G"'' (移動コマンド) を打って、再度ステータス表示コマンドを打つと、表示される場合がある。
