MEGARA: the future IFU and MOS of the 10.4 M GTC

In these proceedings we summarize the characteristics and current status of MEGARA, the future optical IFU and MOS for the 10.4 m GTC. MEGARA is being built by a Consortium led by the UCM (Spain) that also includes the INAOE (Mexico), the IAA-CSIC (Spain) and the UPM (Spain). The MEGARA IFU offers two different bundles, one called LCB with a field-of-view of 14 x 12 arcsec^2 and a spaxel size of 0.685 arcsec yielding spectral resolutions between R=6000-19000 and another one called SCB covering 10 x 8 arcsec^2 with 0.48 arcsec spaxels and resolutions R=8000-25000. The MOS component allows observing up to 100 targets in 3.5x3.5 arcmin^2. In September 2010 MEGARA was selected as the next optical spectrograph for GTC. Its PDR is scheduled for March 2012 with First Light on 2015.

MEGARA control system

MEGARA (Multi-Espectrografo en GTC de Alta Resolucion para Astronomia) is an optical Integral-Field Unit (IFU) and Multi-Object Spectrograph (MOS) designed for the GTC 10.4 m telescope in La Palma. The MEGARA Control System will provide the capabilities to move the different mechanisms of the instrument, to readout the data from the detector controller and the necessary routines for the Inspector Panels, the MEGARA Observing Preparation Software Suite, the Data Factory and the Sequencer strategies.

Making observations with GTC/MEGARA easier: the MEGARA observing preparation software suite

MEGARA (Multi-Espectrografo en GTC de Alta Resolucion para Astronomia) is an optical Integral-Field Unit (IFU) and Multi-Object Spectrograph (MOS) designed for the GTC 10.4 m telescope in La Palma. Its relatively complex layout makes necessary a set of tools to facilitate the observation preparation to the user. The MEGARA Observing Preparation Software Suite (MOPSS) consists on three software components designed to assist observers to optimally plan their observations with GTC/MEGARA: the Exposure Time Calculator, the Image Simulator, and the Fiber MOS Positioning tool. We describe these software tools and the status of their prototypes up to the date.

MEGARA developments at LICA-UCM

LICA-UCM is the brand new laboratory for scientific advanced instrumentation (Laboratorio de Investigacion Cientifica Avanzada) at Universidad Complutense de Madrid where MEGARA integration will take place.

Poem in John Henry Tudor's hand(?), March 1796, with empty envelope

This poem is about winter and appears to be an assemblage of passages from several published works along with Tudor's own compositions. On the verso, Tudor wrote "Abbott 2nd. March 1796." On the empty envelope is written: "Letters from my dear deceased friend J.H.T.," along with a note in another hand reading: "no letters found enclosed." It is unclear whether or not the envelope formerly held the poem.

Poem (manuscript copy owned by Jonathan Remington and Benjamin Parker), 1782

Paper notebook lacking covers with a handwritten copy of John Davis's 1781 Commencement poem titled “Poem. ” The verso of the last page is inscribed: “Benj’a Parker’s property Given him by Remington March 4th 1782.” The last page has a Latin phrase, "Finis cum fistilo jig," and the phrase, "He that has [some] hair cannot wear a wig."

[Excerpt from the poem "Winter"], undated

One leaf containing a handwritten copy of a section of the poem "Winter" by Scottish poet James Thomson (1700-1748). The excerpt begins "'Tis done! dread Winter spreads his latest Glooms," and ends, "And one unbounded Spring encircle all."

[Excerpt from the poem "An Elegy"], undated

Folio-sized leaf containing a handwritten copy of stanzas 13-24 of "An elegy on the late Rt. Hon. W------ P---, Esq," a satirical poem about William Pitt first published in London in 1766. The excerpt begins "Where the dull slave, or Scycophant confess'd," and ends, "And swells quite crimson'd with Britania's Blood." The copy is marked with scribbles.

Valedictory poem delivered in the Chapel of Harvard University on the 21 June 1796: in the presence of the President Proffers & Tutors & the four classes of understudents at the request of the class who completed their college studies on that day

Handwritten draft of the Charles P. Sumner’s valedictory poem to the Harvard class of 1796, in a 19th century hardcover binding beginning “The youth by adverse fortune forced to roam…”. The poem mentions John Russell, a member of the Class of 1796 who died in November 1795. The copy includes edits and struck-out words.

A poem delivered at Harvard College, September 29th, 1789

Eight-page untitled handwritten poem attributed to Harvard student Benjamin Whitwell (Harvard AB 1790). The poem begins “The brow of age is soften’d into smiles” and contains classical and militaristic allusions. An annotation indicates that a set of stanzas beginning, “On thee, our common parent! Guardian! Friend! His mildest warmth, his brightest beams descend….” refers to Harvard President Joseph Willard. The text includes edits and annotations.

Hope: a poem delivered at an exhibition in Cambridge, July 10, 1800

This four-page handwritten poem was composed by Harvard student Joseph Mansfield for a College exhibition on July 8, 1800. The poem begins, "I am not blesd, but may hereafter be; / Who knows what fortune has in store for me?" and concludes with verses about the American Revolutionary War and George Washington.
