Quick Start For Mgenie Users
Libisis is similar to mgenie, but there are some minor differences you should note. Below highlights some of these changes.
set_disk, set_dir, set_ext and set_inst
- set_dir and set_disk have been replaced with set_path. Instead of setting the directory separately, one now sets the path, so
>> set_dir('MAPS/homer_files'), set_disk('c:')
- if set_ext is not used then 'RAW' is assumed
- Although one can assign a RAW file, there are many more options available to read RAW files. See the User Manual.
spec and mspec
- spec is analogous to getspectrum. This reads in an IXTdataset_1d object that you can use, which is similar to an mgenie spectrum
- mspec is analogous to getspectra. This reads in an IXTdataset_2d object that you can use. This is similar to the array of mgenie spectra but contains truely two dimensional information and is different to an array of IXTdataset_1d objects.
- can be given RAW file objects as the first argument also - which will override the automatic behaviour to use the assigned RAW file.
Plotting (dl, mp, da, etc.)
- Can now be given spectra number(s) to plot
- Will plot the spectra numbers given from the assigned RAW file, e.g. dl(553:555) plots spectra 553 to 555 from the assigned RAW file.
- See Plot Commands for more information
- Replaced with a series of Rebunch Functions that perform a similar task
- Note that other Rebin Functions also exist
amark, acolor and aline
- Now accept combinations of sizes and styles in any order - so aline('--','.-',5,6,3,1,3,'..',2') is ok
- Have over advanced options - see Pre-Emptive Formatting for more information
Two Dimensional Operations
- Almost all one dimensional commands have two dimensional extensions
- function_x operates in the x direction while function_y operates in the y direction
- i.e. shift also has shift_x and shift_y commands for IXTdataset_2d objects.
- See User Manual for more information
