Reaction Network for the article: "Piecing together formic acid isomerism in dark clouds. Detection of cis -formic acid in TMC-1 and astrochemical modeling"

The reaction network includes all processes supporting the results of the article “Piecing together formic acid isomerism in dark clouds: Detection of cis-formic acid in TMC-1 and astrochemical modeling” (to appear in A&A).

• Reordered reaction list → Contains the complete set of reactions. Some channels are deactivated (notably those involving isomer-free COOH or HCOOH). A few reactions appear duplicated (e.g., JH + JO → JOH), but the redundant channels are deactivated and therefore not double counted. Caution is advised if branching ratios are calculated including all channels, since even reactions with $\alpha = 0$ are listed.

• itype → Specifies the reaction type (neutral–neutral, photodissociation, etc.) and provides the corresponding reaction indexes in the reordered list for that type.
