This script automaticaly generates the GCN circular draft, which then should be a bit modified (see for fields in <> braces).
The citation of latest GCNs is included. For a successful run a user needs to install 7z archiver first. Its executable
should be globally accessible via PowerShell. This is done by adding the path to 7z to $PATH variable. However, without
7z event when error is occured when downloading the circular archive, the script will be able to download all GCN circulars
one-by-one, starting from #1. But is it desired to do so?
Just run .\make_circular_draft.ps1 and enter source name in the prompt (or specify it with -SourceName option in the PowerShell).
Run Get-Help .\make_circular_draft.ps1 to open the Help on script (this includes list of available options).
The real usage example is shown here:
.\make_circular_draft.ps1 -SOURCE_NAME "GRB 241209B"

Found 8 GCN circulars
GCN draft is in the gcn_draft_GRB 241209B.txt file.
Please, fill the fields that were not automatically filled (in <> bracketes).
The content of the generated GCN circular draft is as follows:
GRB 241209B: <Telescope> optical observations
<Author 1 (Institute)> report on behalf of <team/collaboration>:
We performed optical observations of the field of GRB 241209B (Xie et. al, GCN 38478; Evans, GCN 38494; Perez-Garcia et. al, GCN 38499; Qiu et. al, GCN 38516; Williams et. al, GCN 38525; DeLaunay et. al, GCN 38528; Dafcikova et. al, GCN 38534; Ridnaia et. al, GCN 38537) in the <Filter> filter with <Telescope> of <Observatory> observatory.
The observations began on <Date> <UT> UT, i.e. <Days> since trigger.
The optical counterpart is <DetectedOrNot> in the stacked images.
The preliminary photometry is given below:
Date UT start t-T0 Exp. Filter OT Err. UL(3sigma) Telescope
(mid, days) (s)
<ISODate> <HH:MM:SS> <days:.6f> <n*exp> <Filter> <mag:.2f> <err:.2f> <ul:.1f> <Telescope>
The magnitudes were calibrated using nearby stars from <catalog> and are not corrected for the Galactic extinction towards the GRB 241209B.
Notice, there are fields <days:.6f> that should be update by hand or another software (e.g. using commands similar to sed or regex replacement in PowerShell). Here, after a column sign : a floating point precision is specified (like in default Python f-notation).
Also, it is important to grant rights to execute the script or if one does not want to do it, the content of this script can be copied into locally created .ps1 file.
