Function: skyPlacer()

function skyPlacer(
   aimAzDeg, 
   aimAltDeg, 
   lens, 
   width, 
   height, 
   opts?): (azDeg, altTrueDeg, refractThis?) => SkyPlacement;

The projection at SkyView's heart as a standalone, pinnable function: build the camera basis for an aim, and return the placer mapping an (azimuth, true-altitude) direction to the image plane under the lens's projection (rectilinear or fisheye), with optional atmospheric refraction. skyView composes this internally; the golden suite pins it directly against the Python reference (astroengine.skyview.place).

Parameters

Parameter	Type
`aimAzDeg`	`number`
`aimAltDeg`	`number`
`lens`	`SkyLens`
`width`	`number`
`height`	`number`
`opts`	{ `pressure?`: `number`; `refraction?`: `boolean`; `tempC?`: `number`; }
`opts.pressure?`	`number`
`opts.refraction?`	`boolean`
`opts.tempC?`	`number`

Returns

(azDeg, altTrueDeg, refractThis?) => SkyPlacement
