INLIST List of sources up to 9999 New image parameters: COORDINA Ra, Dec coordinates IMSIZE Ra, Dec number of pixels CELLSIZE Ra, Dec increments in asec APARM (1) Frequency (GHz) plane 1 (2) increment (GHz) (3) number channels ---------------------------------------------------------------- MODSP Type: TASK Use: This task can be used to modify a pair of existing image cubes of either I/V or RR/LL polarization or create new ones. The idea is to make spectral-line image cubes with or without RR/LL differences. Adverbs: INNAME.....Input I or RR image name (name). No default. INCLASS....Input I or RR image name (class). Standard defaults. INSEQ......Input I or RR image name (seq. #). 0 => highest. INDISK.....Disk drive # of input I or RR image. 0 => any. IN2NAME....Input V or LL image name (name). No default. IN2CLASS...Input V or LL image name (class). Standard defaults. IN2SEQ.....Input V or LL image name (seq. #). 0 => highest. IN3DISK....Disk drive # of input Q image. 0 => any. OUTNAME....Output image name (name). Standard defaults. Outclasses are IMODEL, QMODEL, and UMODEL OUTSEQ.....Output image name (seq. #). 0 => highest unique. OUTDISK....Disk drive # of output image. 0 => highest number with sufficient space. BLC........Bottom right corner in input image of desired subimage. Default is entire image. TRC........Top right corner in input image of desired subimage. Default is entire image. FLUX.......Noise level to be added (in the units of the image) FACTOR.....Factor by which the original data is multiplied before it is added to the model. 0 => drop original data. INLIST.....Text file containing one line per source, giving RR, LL, X, Y, Maj, Min, PA, type, line center, width, Dlc/Dx, Dlc/Dy, Dw/Dx, Dw/Dy blank separated free format and trailing zeros FOLLOWING WIDTH may be omitted. The resulting NGAUS will be the number of non-comment lines in INLIST. Limit 9999. (1) The RR and LL brightness is in Jy/beam; (2) The component coordinates and size are X, Y, Maj and Min are in pixels, PA in degrees; (3) Types are point, Gaussian, uniform disk, uniform rectangle, optically thin sphere, and exponential for code numbers 1 through 6. Other values -> 2. (4) line center and width of line (FWHM) are in channels (5) line center and width may vary linearly in x and y away from the stated values away from the component center in channels/pixel Blank lines and lines beginning with # or ; (semi-colon) are taken as comments If making a new image (INNAME blank with I polarization or INNAME and/or IN2NAME and/or IN3NAME blank with I, Q, U) use COORDINA...RA (hours minutes seconds of time), declination (degrees, minutes, seconds of arc) for reference pixel (at image center). IMSIZE.....X, Y image size in pixels CELLSIZE...X, Y image spacing in arc sec APARM......(1) Reference frequency at first output plane in GHz (2) Increment in frequency in GHz (3) Number of frequency pixels ----------------------------------------------------------------
