Function: irim_rdsnip Purpose: read a detector snip into a scan_type variable Category: IRAS Author: Do Kester Use: int irim_rdsnip( fchar irds, IN name of irds fint snipnr, IN sequential snip number fint sdet, IN sequential detector number fint coornr, IN number of plate coord system fint prid, IN requested projection type scan_type *scan ) OUT scan data Returns: 0 : OK error originating from irds_rd_bphf or irds_rd_samples. Description: The intensity data of `snipnr,sdet' is read from `irds'. The bphfinfo is also read and trnsformed into projected coordinates in the plate system. The coordinates are in degrees with the x-axis inverted (increasing to the left: looking inside-out). The sine and cosine of the twist angle is calculated. Comment: This routine is not callable in FORTRAN Updates: 20 Aug 1991: DK, Creation date 05 Aug 1992: DK, into the system
