MUSE_exp_Combine and MUSE_cube_combine

The problem was that the IMAGEFOV that I was using as OUTOUT_WCS didn’t have the right information about the third axis (wavelenght). I had to modify the header of the image including the following information about the third axis:

NAXIS = 3 NAXIS3 = 3681 CTYPE3 = ‘AWAV’ CUNIT3 = ‘Angstrom’ CD3_3 = 1.25 CRPIX3 = 1. CRVAL3 = 4749.75341796875 CD1_3 = 0. CD2_3 = 0. CD3_1 = 0. CD3_2 = 0.

To get the OUTPUT_WCS working I did the following process:

  1. Open a Datacube with all the wavelength and save as image in QFitView.
  2. Then modify the header of the previously exported image to add or modify the keywords mentioned above. I did with some trouble in vim. There must be a better way.

This process is to be able to get the resulting wavelength limited DATACUBE from the recipe muse_exp_combine with the full wavelength range. It will have NaN for the wavelengths that are outside the specified wavelength range in the muse_exp_combine.rc. After the three datacubes (red,green and blue) are created they can be combine with muse_cube_combine.

RAM Memory

The server now has more ram memory. I think 64 GB, so now I can run the recipes in parallel with the options in some of the recipes nifu=-1.

White Dwarfs

Look for info on White Dwarfs population and type of CVs. Most should be magnetic.

Questions

  • [x] Can run without checksum? Will do this. At least for scibasic and scipost

To-Do

  • [x] Combine the four exposures of the center of the cluster taken the first night.
  • [x] Update params of other days with correct recipe directory and maybe that it doesnt do the checksum. Still dont know why didnt work the checksum after changed to new CPL.
  • [x] Re-run everything with new recipe version. For first and second night.
  • [x] Create cleanmastersof with new data from second day of observation. And ran all the recipes.
  • [x] Get all the offsets to combine the datasets.
  • [x] Figure out how to use [ZAP](???). Easy way in the command line python -m zap INPUT_CUBE.fits
