Preparations

1. antstat is running on aste-1c

2. Aspirin is running on aste-1c

Current time = 2015/04/06 01:22:06    <--- The time differences among these three time
Aspirin time = 2015/04/06 01:22:04    <--- should be less than 60 seconds.
Weather time = 2015/04/06 01:22:01    <---
Aspirin Offset : (Az, El) = (   8.65,   4.62 )
Aspirin status : OK ( C22:on  C6:OFF WIND:OFF)  <- should be "OK" and not "WIND_ON"
Refraction Corr. status : OK                    <- should be "OK"

3. (dAz, dEL) is (0.0, 0.0)

4. OPT image

5. Start iOPT

Measurements

  1. Start measurements
    Group:   asteXX
    Project: optXX
    ObsTable: select an observation table close to starting LST
              (e.g. L14h30m.start at LST14:40)
    1. Observation tables shall be updated every year so as to take account of proper motions of stars.
    2. An execution roughly runs for about 80 minutes.
    3. 測定の視野は+-10秒角である (10.5秒とかの数値を表示したら、星像が視野の淵にいる。)星が全く見えない場合、星を長時間trackingする指示書を流して全視野撮像する(5へ)
