dish.flag - Function

	Package	dish
	Module	dish
	Tool	dish

Flag data based on various specifications.

Synopsis
flag(scan, ints, polarization, channel, flag)

Description
This function allows a simple non-GUI means of flagging data; the viewer and msplot allow GUI flagging of data. If no scan is specified, it will flag all scans in the data according to the other parameters (e.g., all channels within a range can be flagged in this way). If no integration is specified, it will flag all integrations. If no polarization is specified, it will flag all polarizations. If no channel is specified, it will flag all channels. If you wish to unflag data, use flag=F.

Arguments

scan		scan number(s) to flag
		Allowed:	integer or vector of ints
		Default:	F
ints		integration number
		Allowed:	integer or vector of ints
		Default:	F
polarization		polarization number(s) to flag
		Allowed:	integer or vector of ints
		Default:	F
channel		channel (range) to flag
		Allowed:	integer or vector of ints
		Default:	F
flag		flag (T) or unflag (F)
		Allowed:	boolean
		Default:	T

Returns
T (if successful)

Example

d.open('stjul13SP');
d.gms();
d.plotc(36)
d.flag(36,channel=100:120)      #flag all subscans, polarizations of scan 
                                #36 in the channel range of 100:120
d.plotc(36)                     #you should see the range masked
d.flag(36,flag=F);              #unset all flagging
d.plotc(36)                     #it's back!
d.flag(36,channel=500:550,polarization=1)
d.plotc(36)                     #you should see a gap just in the first 
                                #polarization
d.flag(36,flag=F);
d.flag(36,1)                    #flag just the first integration
d.plotc(36)                     #should look okay though it doesn't 
                                #include the first integration
d.plotc(36,1)                   #masked
d.plotc(36,2)                   #okay
