smalod% inp Task: smalod in = /sma/data/040329_09:37:37/ % import raw data in SMA archival format. out = gc % prefix of output file name in MIRIAD format. rxif = 1 % rx/if id =1 sideband = 0 % lower side band. nscans = 35,950 % skip the first 35 integration scans. % and load the next 950 scans.For observations with dual receiver system, selection above will load only the lower side band data of one receiver (with a receiver id=1) from the original SMA data file. A total of 4 seperated files will be splitted from a raw SMA data file observed with a dual receiver system. Miriad supports calibration of the splitted data based on each of frequency bands.
Since the version 1.15 11-Oct-05 or a later version, smalod has been implemented with a function of reading the online flagging information by default. In addition, in case of the corrupted baseline vectors in the SMA data header which is used to decode the antenna positions of the array, there is an input Keyword: readant which allows users to read the ASCII file 'antennas' in the SMA file data directory if readant=8 or larger number is specified. Here is an exmaple of the usage:
smalod in=050911_04:21:35 out=050911H30a rxif=0 \ sideband=1 nscans=5, readant=8
Note that for the data taken from 4 GHz mode, smalod reads the antenna positions directly from the ASCII file 'antennas'.
