# Dirty Sumfiles

### Basic Description

This is a MATLAB code that creates sumfiles and nominals, so that they can be used to create images for SPC. The MATLAB code is made up of two files. The first being a MATLAB function that calculates the pointing vectors to be placed in the sumfiles and nominals. The second file is a MATLAB script that generates the sumfiles and nominals.

NPX, NLN, THRSH - Pic size, lower and upper dn thresholds. Code does not generate these, but are inputs.

• Map/Sam/Polycam - 1024  1024     5 16383

MMFL, CTR - Focal length, px/ln center (boresight/optical axis). Code does no generate these, but are inputs.

• Mapcam - 0.1250000000D+03    0.5115000000D+03    0.5115000000D+03

• Samcam - 0.0240000000D+03    0.5115000000D+03    0.5115000000D+03

• Polycam - 0.6110000000D+03    0.5115000000D+03    0.5115000000D+03

SCOBJ - s/c to object vector (Object Body Fixed)

CX - pixel unit vector (Object Body Fixed)

CY - line unit vector (Object Body Fixed)

CZ - boresight unit vector (Object Body Fixed)

SZ - Object center to sun unit vector (Object Body Fized)

K-MATRIX - ?

DISTORTION - ? recommended to keep zero

SIGMA_VSO - formal scobj uncertainty

SIGMA_PTG - formal pointing uncertainty

### Code Inputs

The majority of the code inputs are placed within the first 20 lines of the Dirty_SUMFILES.m script. An example is shown below:

```% Dirty_SUMFILES
% 09/10/15

clear all
clc

distance_sc_vec = [0.740740740751991 2];
size_d = size(distance_sc_vec);

BENNU2LMRK_mat = [  -0.3311398748D-01    0.2609513595D+00   -0.3709481280D-01]';
size_m = size(BENNU2LMRK_mat);

naming_vector = ['C'; 'b'];

for azimuth_sc = 0:20:340;
for zenith_sc = 45;
for azimuth_sun = 135;
for zenith_sun = 30;
for b = 1:size_d(2);
for n = 1:size_m(2);             ```

distance_sc_vec - is a vector that contains the distance(s) between the spacecraft and the landmark the camera is pointing at. Make sure it is a row vector.

BENNU2LMRK_mat - is a vector of object center to the landmark the camera is pointing at (Object Body Fixed)

naming_mat - rows are for distance and columns for landmark pointing to.

azimuth_... - azimuth angle (NEZ frame)

zenith_... - zenith angle (NEZ frame)

b - don't change (not input)

n - don't change (not input)
