make_sumfiles.txt

Description

This configure file contains basic camera distortion data and a list of available SPICE kernels. It is used by make_sumfiles as a configuration file when generating SUMFILES and NOMINALS. At this time, make_sumfiles.txt is created by hand.

Creating make_sumfiles.txt

Here is a sample make_sumfiles.txt" file. Annotations on the right indicate what the data elements are.

The make_sumfiles.txt file consists of three sections:

Camera Data Definitions

Enter the number of cameras that the file maintains (NCAM). List the following for each camera:

• Camera Name
• Pixels (sample and rows)
• Focal length, center pixel (x/y)
• K Matrix - distortion matrix
• Min and max expected DN for this data type

Enter sigV0 - The uncertainty of the spacecraft position [km] Enter sigPt - The uncertainty of the camera pointing [Rad]

Target Information

• didn't know what to call this "section"--is that heading good?

Enter the follow three rows:

• the names of the ID of the target body
• body fixed frame in the kernels
• aberration correction desired

Kernel List

If the SPICE kernels are not in your working directory, give the path to the kernels (PREFIX).

Start the SPICE kernels list with these two rows:

•  KERNELS
   #

List each kernel on a separate row.

• When in doubt, list all the available kernels.

Here is a list of kernels that are known to make make_sumfiles work:

• SPK kernels (.bsp) - for spacecraft and target object - ephemeris

• CK kernels (.bc) - orientation/attitude of spacecraft and other structures (like camera)

• SCLK kernels (.tsc) - spacecraft clock coefficients

• IK kernels (.ti) - instrument geometry for camera taking pictures

• LSK kernels (.tls) - leap seconds

• FK kernels (.tf) - reference frame specifications

• PCK kernels (.tpc) - text form of planetary/asteroidal constants

End the kernels list with this row:

•  END_KRNLS

When processing make_sumfiles

• If you get the "NOFRAMECONNECT" error (display says, "At epoch...") - You likely need a CK Kernel (<filename>.bc).

• If you get the "SPKINSUFFDATA" error (display says, "Insufficient...") - You likely need a SPK Kernel (<filename>.bsp).
