DATA_SET_TERSE_DESCRIPTION |
Data from the Micro-Imaging Dust Analysis System of the ROSETTA
Orbiter collected in the CRUISE 4-1 mission phase.
|
DATA_SET_DESCRIPTION |
This dataset includes MIDAS data from the ACTIVE CHECKOUT phase #8.
Please note that images acquired during a passive observation are
taken w/o approaching the surface and don't contain meaningful data.
The current release is based on the results of the Comet Science
Reviews held in Feb 2016, Oct 2017 and Oct 2018 and contains the
updates defined in the MIDAS Enhanced Archive Data Delivery contract.
Updates from V1.0
-----------------
Several updates were made in response to the Comet
Science Reviews held in February 2016 and October 2017. Updates have
been made to
- Documentation: MID_EAICD.ASC|PDF, MID_COOR.ASC|PDF (/DOCUMENT)
- Data browser : Updated ReadPDS library to V4.9 (/DOCUMENT/CODE)
- Label files : Added X/Y scaling factor for images (/DATA/IMG/*.LBL)
- Data files : Enhanced history files (/DATA/CAH*.TAB|TGH*.TAB)
- Catalog files: Updated to latest versions (/DOCUMENT/CATALOG)
- This file: : Improved image list facilitates data file referencing
The former updates were done in V2.0 for comet phases but for
pre-comet phases like this one V2.0 was never generated and these
changes were implemented directlly in V3.0.
Additionally Version 3.0 implements the dataset improvements agreed
in the MIDAS Enhanced Archive Data Delivery Contract work packages
101, 102 and 302:
- General : Updated contact names and addresses (VOLDESC.CAT)
Updated dataset content description (AAREADME.TXT)
- Documentation: Updated DOCINFO.TXT, MID_EAICD.ASC|PDF (/DOCUMENT)
Added image scan table MID_IMG_CATALOG.TAB|LBL
Added tip mapping table MID_TIP_CATALOG.TAB|LBL
Added enhanced calibration report MID_CALIBRATION.PDF
Added reconstructed images report MID_REC_IMAGES.PDF
Added tip image catalogue MID_TIP_IMAGES.PDF
Added MIDAS analysts notebook MID_ANALYSTS_NBOOK.PDF
Added MIDAS science user guide MID_SCI_USER_GUIDE.PDF
- Data files : Recalibrated images in X/Y/Z based on the evaluation
of the results from the calibration target scans
Complemented dataset with reconstructed images
Added particle mask image files (DATA/IMG/*_MK.IMG)
Added document links to detached label files
Added browse images for PSA (/BROWSE/PRV_*_ZS.JPG)
Fixed HORIZONTAL/VERTICAL_PIXEL_SCALE calculation
Fixed xlength/ylength calculation in image files
Fixed number of columns in ROI and SPA data products
- Catalog files: Updated to latest versions (/DOCUMENT/CATALOG)
- This file : Marked reconstructed and mask images in image list
The following images can be found in the dataset (for a given image,
the name of the respective label file is composed of the file path
associated with the preceding medium term planning period MTPxxx and
the image identifier listed in the second column):

CONFIDENCE_LEVEL_NOTE |
Confidence Level Overview
=========================
All telemetry data frames produced by MIDAS contained checksums
that were validated upon ground receipt.
During the processing of the data in preparation for delivery
with this volume, the structure of the telemetry data packets
was verified. This verification included detection of both the
DDS header and the length of each packet, which ensured that all
packets were complete and not damaged.
The validity of the data has been approved by the MIDAS Science
Lead and Science team members by review of the included images
and evaluation of the associated housekeeping information.

ABSTRACT_TEXT |
The Micro-Imaging Dust Analysis System (MIDAS) is an instrument on the
ROSETTA Orbiter that will provide 3D images and statistical parameters
of pristine cometary particles, collected in the vicinity of comet
67P/Churyumov-Gerasimenko. This data set includes all data from the
CRUISE 4-1 mission phase.
This release supersedes version 1.0. Version 2.0 was never generated
for pre-comet phases.
