The default values are taken from a file in the current user's directory. Each time a search is made, the coordinates of the first entry found are written to this file for subsequent searches. The RA and Dec can also be given on the command line, with a comma used to separate the RA, Dec, and radius fields. The RA and Dec can be abbreviated to omit the seconds or minutes. For example,
CMA_SOURCES_DEC > sc 18 20,-30,60to make the same coordinate search, but with the cone radius increased to 60 arc minutes. All entries within the specified cone are selected as the subsample and a line summary is given for the entries found. The output from this search is:

This number refers to the entry number in the subsample. The > refers to the default entry. Once a subsample containing one or more entries has been selected, the RA and Dec of the first entry will become the default for the next search. Several search qualifiers are used to modify the search. Using /default will take the default values for the position and cone angle, written from the previous search. The /radius=x uses the default RA and Dec and sets the radius to x arc minutes, /nodefault stops the default RA and Dec being updated after the search and /full lists the search results without pagebreaks.
sp [parameter] [min] [max]This searches for all values of the given parameter within the specified min-max range (inclusively). A listing of the names, numbers, and descriptions of the parameters and their associated numbers can be obtained from the BROWSE command line with the lparm (list parameter) command. The default lists all of the parameters available for the current database. The parameters in another database can also be listed by typing lpa dbname, where dbname specifies the required database name. To list the attributes of each parameter (the data type) type lpa/att dbname. A description of each parameter is given by typing dbhelp par xxx, where xxx is the parameter name. A typical parameter search might be to find all EXOSAT LE count rates between 0.1 and 0.2 as follows:
CMA_SOURCES_NAM 10> sp count 0.1 0.2OR
CMA_SOURCES_COU 213> sp Enter parameter name: count Enter minimum numeric value: 0.1 Enter maximum numeric value: 0.2A list of the parameters can be obtained by typing <CR> in response to the prompt for the parameter name. If the parameter to be searched is a character string, a range or a single value can be specified. For example, the command sp name mkn766 searches for all occurrences of mkn766. Alternatively, sp name 3c100 3c120 searches for all the 3c objects between 100 and 120, inclusive.

Also given are the indexes currently available for each sample and a description of the contents of the sample. The GOOD sample represents all ME observations with a good quality flag. The AGN sample represents all AGN observed by the ME and so on. To change sample, use the csam command.
