SPIRou : tentative budget

The total cost of Spirou is estimated to be about 3 M€.
The budget details (including a 20% overhead on all items), is:

spectrograph optics: 1 M€

spectograph cryomechanics: 1 M€

Cassegrain module & polarimeter (optics & mechanics): 0.4 M€

detector: 0.3 M€

electronics & control: 0.3 M€

This budget is fairly conservative, eg compared to the initial budget estimate of Giano (1.3 M€). We are therefore very confident that the final budget will not exceed this amount.
