Optical telescope setup

Focus adjustment

Display an optical image to check focusing

  1. Login to aste-ms1 with asteXX
    > ssh -Y asteXX@aste-ms1
    • Don't forget to add '-Y' option to forward windows.
  2. Initialize the video capture board (at the start of measurements once a day)
    asteXX@aste-ms1 > ssh astecntl@aste-c1c /cosmos3/naoj/sbinSol/optinit
    device:    [ ok ]
    mmap:      [ ok ]
    init bcr:  [ ok ]
    init:      [ ok ]
    initLUT:   [ ok ]
    clear FB:  [ ok ]
    AVME-338B -> successfully initialized    <--- confirm this message
  3. Display (a part of) an optical image
    asteXX@aste-ms1 > ~/analysis/bin/optshot r  1  32
                                            (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 '224' for a full-size image)
    This will display an image whose center is (256, 256) pixels and size is 32 pixels.
    • ポインティングがあった状態で、星像は概ね(X,Y)=(256,256)近傍に来る
    • Pixel scale is 1.27 arcsec/pixel.

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。
