Test F3H - Latitude

Goal: Physical characteristics of the object. The maximum variation in sub-solar position is a function of the latitude of the TAG site. The higher in latitude the TAG site is, the lower quality the variations in Sun vector. Thus, we can get a better idea about how big this error is as we move to the polar regions.

Test Set Up

Data: Detailed Survey.

Start: 75cm Preliminary Survey Shape Model.

Build: Build TAG Site 1 for each Sub-Test, but using different images than standard. Because the shape model has different topography, we would not be able to build a TAG Site at each latitude and compare results -- RMS is strongly effected by variations in topography. As such, we will adjust the position of the Sun so that the images match the observing/illumination conditions that DS would have if TAG Site 1 was at different latitudes.

Sub-Test F3H-1 to F3H-9

For each Sub-Test, we start with the Preliminary Survey Shape Model. We build the topography using the Detailed Survey Images that are available at each latitude. Images will need to be generated with Bennu with the Sun position that cannot really exist. Either Bennu can be inclined by the needed number of degrees with the pole and date matching the summer solstist, or the SPOC has tools to generate images and SUMFILES for specific illumination geometries. The SPOC has conducted similar variations in illumination parameters so this is well understood. For this test, the SPOC would use Imager_MG to generate the images, which generated almost all of the images needed for Test F2-Calibration. The Test Engineer has compared the output of Freespace and Imager_MG and has determined that the variations between the two systems are not significant.

Evaluate:

Relative Accuracy.

Create truth models for each of the latitude TAG sties.

Then compute the RMS deviation between the truth and the model.

Examples:

Directory Setup

Run from the F3H-Lat directory

0. Start typescript

scriptdatepwdls -l

1. Create Sub-Test directory

rsync --delete -ha orig/ test/

2. Add Sub-Test images

/SPC_Test/F3H-Lat/base/IMAGEFILES/ should already have all the images. We will control the images used by SPC via PICTLIST.TXT

Should also set up a PICTLIST.TXT for each sub-test and put it in lsupport/

Ensure the following states:

Tiled

Correlated

Imaged

Fitted

Geometry ( use 5 .0025 .0001 in RESIDUALS prior to running GEOMETRY)

Residualed ( use 5 .001 .00005)

Re-tiled

Do not ensure Sigma'ed since SIGMAS.TXT doesn't have enough significant figures for the ground sample distance this test requires.

13. Run Stats

14. Archive the test directory

mv test/ F3H-X_archive/ # X is the sub-test number
