GUSTO Data Products and Archiving Plan (suggestion of slides from Craig to Paul & Gary) January 24, 2017 Proprietary Information/Competition Sensitive

GUSTO Science Data is Uniquely Diagnostic GUSTO generates [CII], [NII], and [OI] SPECTRAL LINE MAPS Every pixel has a SPECTRUM that reveals the kinematic structure of the gas Maps can be sliced in different ways to learn about structure of ISM on different scales Spatial-velocity “cuts” to study kinematics Integrated intensity to derive total mass, luminosity,… Map in 2D on sky at a given velocity to identify coherent structures SHOW EXAMPLES OF P-V CUTS, ETC.

Example of 3D Data Cube turns 2D imaging of Galaxy into 3D 809 GHz [CI] from HEAT telescope near l=328o January 24, 2017 Proprietary Information/Competition Sensitive

GUSTO Will Exceed its Science Data Goals Mapping area Angular resolution Spectral Resolution Spectral coverage Survey duration From Level 1 requirements (example: 1.9 THz band): 150 sq.deg. 1.5’ Galaxy 1.0’ LMC 2-5 km/s (2 pixel) 500 km/s <100 days Baseline instrument meets requirements (example: 1.9 THz band): 150 sq.deg. 1.0 arcminute 1.8 km/s (2 pixel) 580 km/s 99 days Total uncompressed data volume to be downlinked: 250 GiB (x 2 margin) On board raw data storage requirement is 600 GiB (x 2.7 margin) January 24, 2017 Proprietary Information/Competition Sensitive

GUSTO has a uniform data strategy 0.8 Mbps bandwidth in Line-of-sight (LOS) mode 0.2 Mbps bandwidth in Over the Horizon (OTH) via TDRSS and Iridium All reference frames are returned at level 0.5 (raw) and source frames at level 1. This allows reconstruction of raw data at a data rate of 0.1 Mbps. Each step in the pipeline will be validated via unit testing on the ground. Level 1 pipeline parameters can be adjusted from the ground as needed January 24, 2017 Proprietary Information/Competition Sensitive

Data Quality Assessment and Decision Tree Most data quality assessment happens in Level 1 processing, performed every OTF row Automated effort to make each spectrum usable. Failure marked per spectrum. Sufficient failures in a given row will mark the entire row as ‘bad’ and necessitate repeating Multiple row failures will flag an error condition in which automatic retuning of that receiver band will be performed Cognizant observer can adjust receiver parameters to assist if necessary RMS within spec? Y OK N Try alternate baseline fit Use alt reference spectrum RMS within spec? Y OK N Mark spectrum bad & repeat January 24, 2017 Proprietary Information/Competition Sensitive

Extensive Ground System Heritage SWAS (SMEX) satellite: data on 4 submillimeter spectral lines stored on board and processed by in-house pipeline developed at FCRAO. [G. Melnick] Sequoia 32-element 100 GHz array on FCRAO 14m telescope: OTF mapping, regridding, and averaging very similar to GUSTO. [P. Goldsmith] HEAT telescope pipeline is recent realization that demonstrates key features of GUSTO processing [C. Kulesa] A strip map spanning G300 through G307 which demonstrates the dynamic Galactic emission from atomic carbon in its 809 GHz line as portrayed through the HEAT telescope’s single channel images (0.5 km/s per channel) depicted from -40 km/s to +30 km/s Vlsr.

Proprietary Information/Competition Sensitive Data Archiving Plan Data archive management led by SAO in collaboration with Arizona Preliminary data release DR0 mirrored at Arizona Cyverse and Harvard Dataverse. Final data release DR1 additionally archived at IRSA for long term storage at end of Phase F. Data access through web interface Open data model: no proprietary period following verification of data calibration and quality January 24, 2017 Proprietary Information/Competition Sensitive

Proprietary Information/Competition Sensitive Data System Summary GUSTO Data Products exceed their Science Requirements with substantial margin. All Level 0/1 data will be returned to the ground using available telemetry. GUSTO’s 3D maps of the Galaxy will be generated on the ground using standard OTF processing techniques. GUSTO’s data will be made available online following the Open Access model with no proprietary period. GUSTO’s data will be available online from long term archives at Arizona, Harvard/CfA and NASA/IPAC. GUSTO’s Data System leverages decades of experience and heritage from both ground and space. It will produce outstanding science at low cost and risk January 24, 2017 Proprietary Information/Competition Sensitive

EXTRA SLIDE: Template for addressing questions Response to Question 00 Use this slide to respond to a review committee question. Update include the question number in the upper right Repeat the question at the top Provide the response to the question – be careful about “over answering” More information than requested may not be a good thing January 24, 2017 Proprietary Information/Competition Sensitive
