GTC operation updates (I)

22

New observing modes and lower overheads in Phase 2 (from S18A onwards)

A new internal tool for detecting collisions between programs (see discussion issues)


GTC operation updates (II)

23

Private data now available trough GTC Archive (details on GTC Archive presentation).

VI Science with GTC meeting finally scheduled for 10-14 December 2018 to be held atUniversitat of Valencia. Maria Rosa Zapatero designed as SOC chair.

Remote control room facility at CALP in progress, available before the end of S18A.

Reduction helpdesk project ongoing (expected before September 2018), availablereduction tools for OSIRIS/CIRCE/EMIR/Canaricam/Hipercam/MEGARA will be providedfor the users, as well as other user’s requests on data management.


Discussion issues (I): Low science productivity

24

We are producing much more science time than ever, with different instruments(OSIRIS / Canaricam / CIRCE / EMIR), but the science productivity is decreasing!!!.

Roughly 50% of GTC papers have a first author from GTC community.

As of February 15th, more than 20 papers published (journal’s backlog?)

Time delay in publishing increases noticeably with time.

A general issue? (see recent ESO survey: https://arxiv.org/abs/1802.03272)

Time delay (years)


Discussion issues (2): TOOs at GTC

25

The number of TOO hours executed haveincreased to 50-70 h in the last years (butalso the time allocated for TOOs hasincreased, so we keep the approximatelythe same rate).

The number of triggers received persemester is now > 70, that means a triggereach 2 nights available for science! (withouttaking into account bad weather, so theeffective rate is even higher!).

TAC decision’s on this regard was not toallocate Q3/Q4 TOO proposals. However,after studying impact of ToO on sciencepublications, results show the highproductivity of this kind of programs.

GTC TOOs triggers rate

The number of TOO hours executed haveincreased to 50-70 h in the last years (butalso the time allocated for TOOs hasincreased, so we keep the approximatelythe same rate).

The number of triggers received persemester is now > 70, that means a triggereach 2 nights available for science! (withouttaking into account bad weather, so theeffective rate is even higher!).

TAC decision’s on this regard was not toallocate Q3/Q4 TOO proposals. However,after studying impact of ToO on sciencepublications, results show the highproductivity of this kind of programs.



27

TOOs programs produced 75 papers, 22% of total number, but using 8% of total time.

4 out of 7 papers in NATURE are from TOOs but GTC contribution is modest.

Discussion issues (3): Target duplications policy

28

The present method to identify duplication failed to identify a collision between anapproved DDT target and a target previously requested via TAC.

This require to refine the procedure to identify possible duplications, and is anopportunity to revise the priority policies such as defining if/when a DDT proposalcan override a TAC allocated program

Depends on the scientific definition on the TAC proposal?

DDT always should have the highest priority?

First come first served basis? (in ESO manner)

Currently under discussion with DDT/TAC committee


Plan for Semester 2018A (time allocated by TACs)

29GTC GUC Meeting IAC, La Laguna, 21 – 22 Feb 2018

Approximately 80 % of time for science

+ MEGARA operational tests.

+ HORS commissioning / EMIR MOS commissioning.

+ Fcass-E preparatory works for Canaricam.

Offer the following OSIRIS functionality:

+ Broad-band imaging (including SHARDS filters)

+ Long-slit spectroscopy

+ Multi-object spectroscopy

+ TF-R & TF-B narrow-band imaging

+ Frame transfer & fast photometry mode, only in visitor mode

Offer EMIR imaging and longslit spectroscopy.

Offer HiPERCAM on a shared risk basis for March-May 2018.

Plan for Semester 2018B (call for proposals early-March)



+ Canaricam commissioning.





+ TF-R / TF-B and NEFER (private use) narrow-band imaging.



Offer MEGARA both IFU and MOS modes (observing window alsoincludes July-August 2018).

Offer HiPERCAM on a shared risk basis for September-October 2018.

OSIRIS


Funds approved by MINECO have been received to start the projectfor a new monolithic 4k x 4k detector (blue sensitive / reducedinterference fringes in red).

Requirements definition process already started looking for anexternal tender. Estimated time about one year since ordering thedetector with the aim of being tested before removing OSIRIS fromNasmyth B.

OSIRIS (+NEFER)


NEFER will supply OSIRIS with a medium-resolution FP for 2Dspectroscopy with R ≈ 20000 (spectral resolution 0.44 – 0.57 A) overthe whole OSIRIS FOV in two spectral ranges: 630 to 700 nm and800 to 900 nm, by using up to 6 different blocking filters.

Only direct use in OSIRIS will be considered (identified as phase 1 inthe instrument team’s proposal).

NEFER integration tests were done on December 2017 with verysatisfactory results. Module easily incorporated in OSIRIS with nointerferences with remaining instrument functionalities.

Short test images taken on sky shown very promising results in termsof efficiency.

NEFER will be included in the call for proposals for S18B as a privatefilter only available to the instrument team (P.I: Margarita Rosado,UNAM, México).

HORS


HORS commissioning in September 2017 was cancelled due to a gasleakage in one of the Cryotiger’s hoses, that need to be repaired.

A tight schedule for night commissioning in the telescope. Final datesfor commissioning have been agreed to be done on April 2018.

EMIR

EMIR started a maintenance shutdown on30 October 2017 that lasted 2.3 months. Maingoals:

Preventive maintenance of cryocoolers: as permanufacturer’s recommendations the 4coldheads were refurbished (new displacer andmoving parts) and new adsorbers (filters) wereinstalled in the two He compressors.

Preventive maintenance on CSU: replacementof all (110) friction pads (because of wear),upgrade old piezo of the slowest bars for thenew piezo type, and clean debris.

Correction of detector tilt: aiming to improvethe image quality across the FOV, that wasstrongly degraded with a significant portion ofthe detector being out of focus.

Other maintenance tasks and inspections.


EMIR

Cold tests and recalibrations begun on 29 December 2017 and are still ongoing:

36

CSU: under investigation. The initially worse performance is now improving (currentreconfiguration (TBC) time of the order of 7 min , vs. nominal value of 5 min). Possiblecauses:

- Too high pre-load on the actuator’s pad (may improve with time as the pad wearsout)

- Electronic issues

- CSU too cold

- Other?

Cryogenic performance is best than ever:best vacuum (2E-7 mbar) and muchcolder (indeed a bit too cold), with theOptical Bench @ 60K.

After

Focus range: -627 -> -453 um

Residual tilt ~ 4.8 mrad

Before

Focus range ~ -900 -> -400 um

Detector Tilt has been reduced (from ±250 ummaximum defocus to ±87 um now).

This residual (~4.8 mrad) is explained byan initial sub-estimation of the real tilt


EMIR


Noticeably improvement inthe IQ after tilt correction.

MOS commissioning hasbeen scheduled on March -April 2018 (10 nightsallocated in two periods).
