Finalise observation parameters

[Joshuaalbert]

@varosero I think the best way to go forward is use the survey pointings, then pick a tile from from it, and position TRECS over the central pointing in the tile. Because, the hex pattern will change at different RA/DEC (not only over DEC). I'll save the output of the equidistant tiling into a txt file, and put into the assets.

To get them they are:

fill_registries()
survey_pointings = misc_registry.get_instance(misc_registry.get_match('survey_pointings'))
print(survey_pointings.survey_pointings_v1())
