P3.13 Center the slit

• Phase : 3
• Status : Draft
• Category : Nighttime testing (functionality and operability) (C4)
• Recurrence : once at commissioning
• Duration : 4 hours

Description

• This activity will center the long slit.

Prerequisites

• Atmospheric conditions: AO working conditions.
• Authorize SHARK-NIR on the SX side.

Procedure

• Point to known binary stars and then offset the telescope and the rotators to get to the nominal (known) position of the planet or introducing a bright speckle by using secondary mirrors at the same parallactic angle of the planet in order to align the slit or TBD????? [This procedure is not complete. we need to work on this.]

Comments

• define the procedure.
• ask VD and DM if (1) SPHERE has a LSS mode and if yes, how they do it ? and (2) do you think need to have a preliminary image of the star + planet (without the slit)? DM: Yes, SPHERE has a LSS mode. They do not take any preliminary images of star+planet without slit: the planet won't be visible in one-shot images (unless it is extremely bright). Just go to the position

angle of the planet and start the observation. The only monitoring tool we have is to look at the spectra in real time: the planet should appear as a vertical line (not always so easy to spot anyhow). Is it possible to access SCICAM images in real time?
