Here is a list of processes unique to Mercury. Update as needed, and at some point compile into a coherent set of procedures.

Collect calibrated I/F images

• You can use the PDS link here or other location.

• Get the DOY, and down the I/F calibrated cube. (ex. CN0221023175M_IF_5.IMG)

Instructions for making I/F cubes of Mercury

processCalMessenger

Using processCalMessenger.c does not currently (30 July 2020) need an SPC directory. All input and output files just need to be in the directory from which the program is executed.

Note: You'll need to prescreen the images for 512 by 512 and 1024 by 1024. There are separate programs for image size.

• processCalMessenger
• processCalMessenger512

Required Input Files

• <I/F image name>.IMG

• <SPC SUMFILE name>.SUM (12 characters: first letter E or C, 10 digit ephemeris time, filter letter)

Example:

• CN0221023170M_IF_5.IMG
• N0221023170M.SUM

Output Files

Creates new SUMFILE and IMAGEFILE. The output name drops the first character of the input name, and replaces it with a "C".

Example:

• C0221023170M.DAT
• C0221023170M.SUM
• process_calibrated.log

Usage

e.processCalMessenger <PDS calibrated name>.IMG

Ex: e.processCalMessenger CN0221023170M_IF_5.IMG

Wrappers for ingesting calibrated images for I/F

Setup

• Create the folder CDR_Images in the cube directory and fill with calibrated I/F IMG files
• Update the directory calls in the shell wrapper.
• Note that you need to update the processCalMessenger call for 512 images. Can get the 512 images by running...

head -246 *.IMG | grep LINES

• processCalMessengerForIoverF.sh (ignore the tmp and newSUM variables since they aren't used)

Usage

• input list will be the spc names (i.e. N0108826727M)

sh bin/processCalMessengerForIoverF.sh 1024List

Processing and End State

• Shell will copy spc SUMFILE from the designated SPC directory into CDR_Images
• Runs processCalMessenger and save INIT and updates process_calibrated.log
• Delete old spc SUMFILE when finished, and move new SUMFILES and DAT files to "working" directory where I/F cubes will be generated.

Note1: Some of the older ingested images into the Mercury directory use a different naming scheme. For these, process as normal, but copy the SUMFILE to the "working" directory and modify the filename and name in the first line Note2: If you have errors when you run (i.e. some ingested images use a different naming scheme), make sure you modify process_calibrated.log after you've fixed the errors. process_calibrated.log will be used later by rawMosaic, and you don't want old information to be read.

rawMosaic

As of 14 Aug 2020

• The upper threshold generated by processCalMessenger in the output SUMFILE is not that expected by rawMosaic. You'll need to modify the upper threshold in the C_.SUM before running rawMosaic. Change the 4095 to 65535.

• Since the filename of the image has changed, update INIT_LITHOS.TXT to have a distortion matrix entry for the new image names.
• Then, run as normal to generate I/F ascii file. Put the new image name into MOSAIC.TXT, enter the bigmap name, the scale factor for the image comes from process_calibrated.log, and the offset is 0 (zero).
