TIPS dd/mm/yyyy Slide Number 1 of <#>

Sembach - 19 September 2002Slide 2 of 8

Overview

New Instrument Scientist (Scott Friedman) STScI ground system development on schedule Instrument integrated, in alignment at Ball SI Environmental (Thermal-Vac): January/March 2003 SI delivery to GSFC: Late March 2003 Launch: April 2004

– SM4– replace COSTAR

COS Instrument Activities Science instrument news since last TIPS presentation (June ‘02)

– FUV flight detector (with new QE grid) qualified, installed and aligned in instrument

– Fully integrated instrument currently undergoing alignment at Ball> Gaseous N2 purge > Light passed through both NUV and FUV optical paths> Initial “rough” alignment of all optics is excellent

– Fine alignment will begin soon> Problem noted with RAS/Cal chief ray alignment> ABA to be used to calibrate and reset RAS/Cal

– FUV spare detector being assembled > Mechanical assemblies (door, actuators, etc), QE grid installed> Final QE measurement in mid-October

COS Instrument Activities

SI news (continued)– Optic select mechanism (OSM) life test unit undergoing bench testing

> Determine OSM repeatability and stability properties> Necessary for FP-POS (FP-SPLIT) timing and auto-wavecal usage

– Primary D2 lamp in cal-platform failed during pre-alignment platform random vibration / sine burst testing

> Defective lamp, problem understood, replacement lamp to be vibe tested and installed after the N2 alignment testing

– Thermal controller set point issue> Lower than the expected NUV MAMA survivability temperature> Important only in worst-case scenario (extended HST safing / low-

power with several additional problems)

STScI Integrated Scheduling System

Phase 5 development completed– Auto-wavecals completed– All primary science / calibration exposure development is now complete

Phase 6 development is in progress– Bright object protection target screening document drafted, circulated

> Instrument Science Report to be filed (Leitherer)– Initial preparations for SMOV begun

> Discussions initiated with IDT> Meeting at STScI next week (called by Carl Biagetti)

COS “Back-End” Activities

COS Pipeline (CALCOS)COS Pipeline (CALCOS)– Most modules are now complete– Spectral merging procedures for FP-POS positions in progress– Full testing to occur this fall on integrated SI data– Draft of ICD-47 now exists (P. Hodge) and is being reviewed

COS Header KeywordsCOS Header Keywords– Standard header keyword selections/definitions for science and ACQ

exposures completed– Established COS association requirements

COS User Support Development

COS mini-handbookCOS mini-handbook– Provides observers with basic information about instrument capabilities

available in Cycle 13– Finalized with revised FUV detector QE estimates (October distribution)

COS exposure time calculatorCOS exposure time calculator– Spectroscopic ETC requirements revisited (Astronomer Proposal Tools

environment)– COS implementation to occur over next 6 months
