add dedicated IIC commands for SuNSS

Task Normal Done Done arnaud.lefur arnaud.lefur SPS SuNSS Thu, 4 Feb 2021 18:19:45 +0000 Tue, 16 Feb 2021 12:52:27 +0000 Tue, 16 Feb 2021 12:52:27 +0000 ics_iicActor 0 2 <p>One clarification:</p> <p>The SuNSS acquisition sequence is identical to the regular SPS science acquisition sequence, just limited to the single SM: eek starts commanding N-minute science exposures until it is told to stop. The sunssActor only acts when the telescope starts guiding on a new field (or flat-field) and when it leaves the field. It just needs to be able to alert iic about those transitions.</p> <p>See the step ("IIC SPS startExposures" and "IIC SPS finishExposure" steps, or whatever they end up being named) in <a href="https://github.com/Subaru-PFS/ics_iicActor/blob/master/docs/field_command.md" class="external-link" rel="nofollow">https://github.com/Subaru-PFS/ics_iicActor/blob/master/docs/field_command.md</a> &#8211; all the rest of that logic is taken care of outside of PFS, and the sunssActor detects when it has been.</p> <p>Up to you how to wrap those. Could add an <tt>sm=sunss</tt> argument to the main startScienceExposures command (or whatever it is called), or add your proposed command.</p> <p>For the <tt>ICC SPS finishField</tt> step from the <tt>field_command</tt> document, IIC needs to close the shutters immediately and optionally read out. Again, either tweak the main command or add your proposed one.</p> <p>We will not need the proposed <tt>abort</tt> command, I don't think. iic is the actor which decides whether the running exposure is long enough to keep or not. </p> <p>sunssActor will (we hope) be able to tell icc whether the exposure is a flat-field, i.e. <tt>iic expose scienceFlat sm=sunss</tt>, maybe. </p> <p>OK when do you <b>need</b> this <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=cloomis" class="user-hover" rel="cloomis">cloomis</a> ?</p> <p>Good question. Cable B is on the Fiber Monitoring System at the start of this week, but they do intend to switch to SPS "mid-week".</p> <p>It is really not clear yet how well we can currently observe with SuNSS automatically. Even with a single instrument we expect to be "good" for us &#8211; HSC &#8211; different nights show different patterns and some patterns will require more knowledge. What I'd saying is that we do need at least <tt>startSuNSS exptime=</tt> and <tt>finishSuNSS</tt>, but might well need more later.</p> <p>Those are now implemented :</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>iic sps startExposures exptime=.. iic sps finishExposure iic scienceFlat exptime=.. </pre> </div></div> Development Rank 0|02qpuc:i6001gr068fhw9qo4o0ma Sprint SM1PD-2021 A 2 Story Points 2.0
