To run dopset (the program is available on all of the workstations at the AOC) first create an input file which has to be named ``dopset.inp'' and which has the following format:
The above data card set must begin with a SOURCE card and end with an E-card. the C-, L-, and D-card information may be carried over from one data card set to the next. Each set may have as many as 4 L-cards. Output columns not required will be filled with asterisks. Delimiters may be spaces or commas. Cards with lower than 4 numeric parameters should be terminated with a / and card codes (C, L, D, E, S, Y) have to be enclosed in single quotes.
Optional cards are :
As an example one could prepare the following file called dopset.inp to obtain the sky frequencies for an observation of M33 in the line of HI for two days in February 2009:
M33 'C',013525,304200,/ 'L',1420.40575,-200,1,1/ 'D',41.3,42.1,60,5/ 'Y',2009,/ 'E',/
dopset will look for this dopset.inp file and produce a dopset.dat file containing the frequency information.
A complete listing of all input parameters to dopset is follows:
| SOURCE | source name -- up to 20 characters, may include blanks |
| 'C' | code for coordinate card |
| RA | right ascension(hhmmss.s...) |
| DEC | declination(ddmmss.s...) |
| EPOCH | epoch of above -- if not specified, 1950.0 will be |
| used, and the card has to be terminated with a slash | |
| 'S' | code for site card |
| LONG | site west longitude(dddmmss.s.) |
| LAT | site latitude(ddmmss.s...) |
| ELEV | site elevation (meters) |
| 'L' | code for line card |
| RESTFQ | line rest frequency (MHz) |
| VEL | doppler shift (km s ) |
| VREF | velocity reference system (0=LSR, 1=heliocentric) |
| VDEF | velocity definition (0=radio, 1=optical) |
| 'D' | code for date card |
| STRTDY | first observing day, MST |
| ENDDY | last observing day, MST |
| MINSTP | interval(minutes) between calculations |
| DELHA | hour angle range (hours) |
| 'Y' | code for year card |
| NYR | current year for calculations |
| 'E' | code for end of data set |
