Preliminary synthetic PUNCH data generated from GAMERA model data.

We recommend reading the guides available at https://github.com/punch-mission/punch-5-meeting before using this data.

As data is improved a new version will be released. The first version is in the v1 folder. The second in v2 and so forth.

This data simulates real PUNCH Level 3 data.
It does not include a starfield or F-corona.
The next iteration of this data will include realistic noise.

L3 - Level 3 total brightness and polarized brightness
    PAM - PUNCH Level-3 Polarized Low Noise Mosaic – 32 minutes
    PAN - PUNCH Level-3 Polarized Low Noise NFI Image – 32 minutes
    PTM - PUNCH Level-3 Polarized Mosaic – 4 minutes
    PNN - PUNCH Level-3 Polarized NFI Image – 4 minutes

Data is RICE compressed, and stored in the second HDU. An associated placeholder uncertainty array is stored in the third HDU.

Data can be read in with the default astropy.io.fits libraries. 
With the public release of PUNCH Python tools, a more sophisticated data handler capable of reading PUNCH data and bundling the data and WCS information will be available at https://github.com/punch-mission. 
A sample IDL script for reading PUNCH data is under development at: https://github.com/punch-mission/PUNCH_IDL_Tools

Description of versions:

- v1: the initial version
- v2: fixes WCS misalignment, makes uncertainty more realistic, fixes scaling problem in data
