Setup the optical telescope

Focus adjustment

Display an optical image to check focusing

  1. Login to aste-c1c with asteXX
    > ssh asteXX@aste-c1c
    (Direct login is available from aste-mt1 and aste-ms1.)
  2. Initialize the video capture board (at the start of measurements once a day)
    asteXX@aste-c1c> /cosmos3/naoj/binSol/optinit
    device:    [ ok ]
    mmap:      [ ok ]
    init bcr:  [ ok ]
    init:      [ ok ]
    initLUT:   [ ok ]
    clear FB:  [ ok ]
    AVME-338B -> successfully initialized  <- should be returned
  1. Display (a part of) an optical image
    asteXX@aste-c1c> livecamt R 30 15 256 256 40 
                             (1)(2)(3)(4) (5) (6)

    (2)取り込みフレーム数
    (3)取り込み間隔
    (4,5)切り出すフレームの中心(X,Y)
    (6)切り出すフレームサイズ
    「(X,Y)=(256,256)を中心とする40x40ピクセルの部分画像を表示、30フレーム連続取り込み(表示)、取り込み間隔は15秒 」

Adjust the focus stage position

  1. Run a observation table just tracking a star
    group: asteXX
    project: track
    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
  2. Login to aste-c1c
  3. Connect the stage controller
    asteXX@aste-c1c> tip serial2

"connected" と表示されたら接続成功

※ 接続に失敗した場合

  1. rootになる
  2. admintoolを立ち上げる
  3. 「シリアルポートの設定」を選び
  4. term/2を選び、(ダイアログが開く)
  5. 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)

3. コマンドを逐次入力

Troubleshooting

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。

Procedures to generate observation tables for OPT

1. Run MATLAB on the MTK server (aste-ms1)

You can skip STEP 2-4, if there is no update in the Tycho, FK5 and Hipparcus catalogues.


2. Create a list of bright stars in a MATLAB format

3. Merge additional information to the list

4. Select appropriate stars


5. Generate observation tables

5a. Observation tables for optical pointing

5b. Observation tables for 「いつでもOPT用」

5c. Observation tables for batch execution

5d. ひたすら12時間追尾する指示書
