This is an incomplete description of how to build the ISIS cubes. Portions of this are being filled in over time. JRW 08 Feb 2020
Start here. Steps to build -- The details of how to build cubes.
Fixing errors that showed up during MOSAICX for Phase.
The process for fixing these errors in Phase is the same as for that in Emission. Here I have a different programs and procedures only because the names of files are different.
- Check the original Phase cube to fine a portion of the cube that has no phase (in this case, it will be the "Offset" value from the "meta" file from the merge program.
cd img-{LastFive}
qview rawP-RG3ED1.cub- Update dumpMapLRO_fixErrorsLastFivePhase.f if it does not match the needed location of the image (i.e. upper left, center, upper right, etc.). Search for "checkI =". Change the checkI value and compile if needed. Note: Since I have to keep updating this code, I just leave the output as "a.out".
cd working/ ~/X-files/source/a.out MapName LastFive 1000
- Check the offset value output by the program (you may have to scroll up a lot to find it) and make sure it is close to the value in "NEW_IMAGES/{Modified PDS Img Name}-meta", there will be slight differences due to how the float is saved. If it looks correct, proceed.
mv RG3ED1-fixed-p.txt ../img-{LastFive}/
- Now make the cube and set up all the proper links to have a paper trail...
cd img-{LastFive}
ascii2isis from=RG3ED1-fixed-p.txt to=RG3ED1-fixed-p.cub samples=1415 lines=1415
mv rawP-RG3ED1.txt orig-rawP-RG3ED1.txt
mv rawP-RG3ED1.cub orig-rawP-RG3ED1.cub
relink.sh RG3ED1-fixed-p.cub rawP-RG3ED1.cub
relink.sh RG3ED1-fixed-p.txt rawP-RG3ED1.txt
qview orig-rawP-RG3ED1.cub rawP-RG3ED1.cub- Link the two cubes together so you can zoom in on the same portion of the image. Next we want to make the dark pixels more noticeable. Click the "Contrast Tool" copy the lower number into the higher number, and increment the value by one. Do this for both images. Then zoom in on an area in the orig cube to make sure the pixels have been fixed.
Better, stronger, faster way to make cubes
Bob uses calibrated images (i.e. image ID. ends in C), no need to ever use the engineering images (i.e. image ID ends in E). You do need to re-ingest the calibrated images using e.processLRO-jrw to preserve data values for I/F. e.processLRO-orig re-scales the data values to maximize the number range in bit space, and we don't want that here. Use e.rawMOSAICXjrw to preserve I/F values when writing the I/F file, and phasei to output the angles directly from SPC. Then all you have to do is use ascii2isis!
What to include in a delivery.
- ISIS cube for relevant images (or all images if there are a small number)
- I/F
- Phase
- Incidence
- Emission
- Lat/lon of 4 corners and center of the bigmap (Upper left is 1,1; Center is Q,Q; Lower right is Q*2+1, Q*2+1)
- PDS Image name for all cubes
FlatMap and FlatAlbedo for bigmap
- SHOWMAP for bigmap
