占星家 这是一个 R 库,旨在提供一些有用的例程来显示射电望远镜图像。 该库旨在主要为一些简单的缩放例程提供一些简单的接口。 该库使用来自代码来进行梯度域高动态范围压缩。 ##示例用法 library(FITSio) library(astror) library(png) fits <- readFits("a.fits") imageData = fits$imDat plot.new() rasterImage(slog(imageData),useRaster=T) ll = logLuminance(imageData[,,1]) cl = gradientDomainHDRCompression(ll) gm = luminanceToGray(cl) writePNG(gm, "test.png") ll = extractLuminance(imageData[,,1
