DHT31_Quad3_interp.fits

DHT31 v-l-b FITS cube, interpolated. In each spectrum, <= 2 missing channels are filled by linear interpolation. In each spatial plane, single missing pixels are filled by linear interpolation, first in l direction, then b.经插值处理后的DHT31 v-l-b型FITS（Flexible Image Transport System）立方体。针对每条光谱，若存在不超过2个缺失通道，将采用线性插值法进行填补；在每个空间平面中，单个缺失像素将通过线性插值法完成填补，填补顺序为先沿l方向，再沿b方向。
